FAB-3583 systemtest placeholders, readme

Includes:
+ updated daily README file in this patch request

+ a simple sample test scripts driver/wrapper, to show syntax
  to enable others to easily include tests in the daily and
  weekly CI test suites (these are in the daily and weekly
  folders, to be kicked off by jenkins in separate jobs -
  not to be confused with many other unit-tests and behave
  tests that are run with every checkin)

+ in addition to the sample, this includes also a
  python driver for system tests written with PTE

Any new tests can be written using any type of language
and simply incorporated into a python wrapper like this.

Note this driver will produce xml output, which
Jenkins will use as input to a display board.

Jenkins jobs will be created to execute some of these
tests as part of a daily test suite, as well as a
longer, weekly test suite.

In the test_pte.py driver, some planned PTE system testnames and
comments are added - but are currently stubbed out with a
TestPlaceholder, so those tests will fail (as planned - until
the actual tests are inserted as they become available).
For instance, executing the weekly test suite (only 2 tests)
currently would produce the following:

```
  $ cd .../fabric/test/regression/weekly
  $ py.test -v --junitxml results.xml ./test_pte.py
  ============= test session starts =============

+# Daily Test Suite
+
+This readme explains everything there is to know about our daily regression test suite.  *Note 1*: This applies similarly for both the **test/regression/daily/** and **test/regression/weekly/** test suites.  *Note 2*: The Release Criteria (**test/regression/release/**) test suite is a subset of all the Daily and Weekly tests.
+
+- How to Run the Tests
+- Where to View the Results produced by the daily automation tests
+- Where to Find Existing Tests
+- How to Add New Tests to the Automated Test Suite
+  * Why Test Output Format Must Be *xml* and How to Make It So
+  * Alternative 1: Add a test using an existing tool and test driver script
+  * Alternative 2: Add a new test with a new tool and new test driver script
+  * How to Add a New Chaincode Test
+
+## How to Run the Tests, and Where to View the Results
+
+Everything starts with [runDailyTestSuite.sh](./runDailyTestSuite.sh), which invokes all test driver scripts, such as **test_pte.py** and **test_chaincodes.py**. Together, these driver scripts initiate all tests in the daily test suite. You can manually execute **runDailyTestSuite.sh** in its entirety, or, run one any one of the test driver scripts on the command line. Or, you may simply view the results generated daily by an automated Continuous Improvement (CI) tool which executes **runDailyTestSuite.sh**. Reports are displayed on the [Daily Test Suite Results Page](https://jenkins.hyperledger.org/view/Daily/job/fabric-daily-chaincode-tests-x86_64/test_results_analyzer). When you look at the reports; click the buttons in the **'See children'** column to see the results breakdown by component and by individual tests.
+
+#### Where to Find Existing Tests
+
+Examine the driver scripts to find the individual tests, which are actually stored in several locations under **/path/to/fabric/test/**. Some tests are located in test suite subdirectories such as
+
+- **test/regression/daily/chaincodeTests/**
+
+whereas other tests are located in the tools directories themselves, such as
+
+- **test/feature/ft/** - User-friendly *Behave* functional tests feature files
+- **test/tools/PTE/** - Performance Traffic Engine *(PTE)* tool and tests
+- **test/tools/OTE/** - Orderer Traffic Engine *(OTE)* tool and tests
+
+Each testcase title should provide the test objective and a Jira FAB issue which can be referenced for more information. Test steps and specific details can be found in the summary comments of the test scripts themselves. Additional information can be found in the README files associated with the various test directories.
+
+## How to Add New Tests to the Automated Test Suite
+
+We love contributors! Anyone may add a new test to an existing test driver script, or even create a new tool and new test driver script. The steps for both scenarios are provided further below as *Alternative 1* and *Alternative 2*. First, a few things to note:
+
+- Before linking a test case into the CI automation tests, please merge your (tool and) testcase into gerrit, and create a Jira task, as follows:
+
+  1. First merge your tool and tests to gerrit in appropriate folders under **/path/to/fabric/test/**.
+  1. Of course, all tests must pass before being submitted. We do not want to see any false positives for test case failures.
+  1. To integrate your new tests into the CI automation test suite, create a new Jira task FAB-nnnn for each testcase, and use 'relates-to' to link it to epic FAB-3770.
+  1. You will this new Jira task to submit a changeset to gerrit, to invoke your testcase from a driver script similar to **/path/to/fabric/test/regression/daily/test_example.py**. In the comments of the gerrit merge request submission, include the
+      - Jira task FAB-nnnn
+      - the testcase title and objective
+      - copy and fill in the template from Jira epic FAB-3770
+  1. Follow all the steps below in either *Alternative*, and then the test will be executed automatically as part of the next running of the CI daily test suite. The results will show up on the daily test suite display board - which can be viewed by following the link at the top of this page.
+
+#### Why Test Output Format Must Be *xml* and How to Make It So
+
+The Continuous Improvement (CI) team utilizes a Jenkins job to execute the full test suite, **runDailyTestSuite.sh**. The CI job consumes xml output files, creates reports, and displays them. *Note: When adding new scripts that generate new xml files, if you do not see the results displayed correctly, please contact us on [Rocket.Chat channel #fabric-ci](https://chat.hyperledger.org).* For this reason, we execute tests in one of the following ways:
+
+  1. Invoke the individual testcase from within a test driver script in **regression/daily/**. There are many examples here, such as **test_example.py** and **test_pte.py**. These test driver scripts are basically wrappers written in python, which makes it easy to produce the desired junitxml output format required for displaying reports. This method is useful for almost any test language, including bash, tool binaries, and more. More details are provided below explaining how to call testcases from within a test driver script. Here we show how simple it is to execute the test driver and all the testcases within it. *Note: File 'example_results.xml' will be created, containing the test output.*
+
+  ```
+     cd /path/to/fabric/test/regression/daily
+     py.test -v --junitxml example_results.xml ./test_example.py
+  ```
+
+  1. Execute 'go test', and pipe the output through tool github.com/jstemmer/go-junit-report to convert to xml. *Note: In the example shown, file 'results.xml' will be created with the test output.*
+
+  ```
+     cd /path/to/fabric/test/tools/OTE
+     go get github.com/jstemmer/go-junit-report
+     go test -run ORD77 -v | go-junit-report >> results.xml
+  ```
+
+  1. *If you know another method that produces xml files that can be displayed correctly, please share it here!*
+
+### Alternative 1:  Add a test using an existing tool and test driver script
+
+To add another test using an existing tool (such as **PTE**), simply add a test inside the existing test driver (such as **test_pte.py**). It is as simple as copying a block of ten lines and modify these things:
+
+  1. Insert the testcase in the correct test component class and edit the test name
+  1. Edit the testcase description
+  1. Edit the specified command and arguments to be executed
+  1. Edit the asserted test result to be matched
+
+Refer to **test_example.py** for a model to clone and get started quickly. The testcases should use the format shown in this example:
+
+  ```
+      def test_FAB9876_1K_Payload(self):
+        '''
+        Launch standard network.
+        Use PTE stress mode to send 100 invoke transactions
+        concurrently to all peers on all channels on all
+        chaincodes, with 1K payloads. Query the ledger for
+        each to ensure the last transaction was written,
+        calculate tps, and remove network and cleanup
+        '''
+        result = subprocess.check_output("../../tools/PTE/tests/run1KPayloadTest.sh", shell=True)
+        self.assertIn(TEST_PASS_STRING, result)
+  ```
+
+### Alternative 2:  Add a new test with a new tool and new test driver script
+
+Adding a new test with a new tool involves a few more steps.
+
+  1. Create and merge a new tool, for example, **/path/to/fabric/test/tools/NewTool/newTool.sh**
+  1. Create a new test driver script such as **/path/to/fabric/test/regression/daily/test_newTool.py**.  Model it after others like **test_example.py**, found under driver scripts under **/path/to/test/regression/daily/** and **test/regression/weekly/**.  Note: the filename must start with 'test_'.
+  1. Add your new testcases to **test_newTool.py**. The testcases should use the following format. Refer also to the steps described in Alternative 1, above.
+
+  ```
+    class <component_feature>(unittest.TestCase):
+      def test_<FAB9999>_<title>(self):
+        '''
+        <Network Configuration>
+        <Test Description and Test Objective>
+        '''
+        result = subprocess.check_output("<command to invoke newTool.sh arg1 arg2>", shell=True)
+        self.assertIn("<string from stdout of newTool that indicates PASS>", result)
+  ```
+
+  1. Edit **/path/to/test/regression/daily/runDailyTestSuite.sh** to run the new testcases. Add a new line, or append your new test driver scriptname **test_newTool.py** to an existing line:
+
+  ```
+     py.test -v --junitxml results.xml test_example.py  test_newTool.py
+  ```
+

+# Daily Test Suite
+Click here for the latest daily status report (WIP: link TBD)
+
+## Running tests
+The entire suite of tests may be executed from script [runDailyTestSuite.sh](runDailyTestSuite.sh).
+Refer to that script for more details about how to invoke each test.
+
+## Adding new tests
+Contributors may add a new test to an existing related test tool group, or create a new one.
+Some examples:
+
+1. To add another test to an existing test suite subgroup, such as
+   the Performance Traffic Engine (PTE) tool,
+   add a test inside the existing python wrapper test_pte.py.
+   The header comment section inside that script contains
+   detailed steps explaining how to do so. In brief, it is as simple as
+   copying a block of about nine lines and modify three things:
+
+```
+   (A) edit the testcase comments
+   (B) edit the line which specifies the command and arguments to execute
+   (C) edit the line that specifies the test result to be matched
+```
+
+2. To add a new test with a new tool, it involves a few more steps:
+
+```
+   (A) Create and merge a new tool such as .../fabric/test/tools/NewTool/newTool.sh
+   (B) create a new file .../fabric/test/regression/daily/test_newTool.py
+       and define a python wrapper to invoke the new tool.
+       Model it after others like test_example.py; the file should
+       contain a testcase that looks something like this:
+
+       def test_TLS(self):
+          '''
+          FAB-2032,FAB-3593
+          Network: 2 Ord, 5 KB, 3 ZK, 2 Org, 4 Peers, 10 Chan, 10 CC
+          Launch network, use NewTool to wreak havoc on the network by
+          doing something crazy, and ensure the network handles it gracefully.
+          Then remove network and cleanup.
+          '''
+          result = subprocess.check_output("../../tools/NewTool/newTool.sh arg1 arg2", shell=True)
+          self.assertIn("A STRING from stdout of NewTool that indicates PASS", result)
+
+   (C) add lines at the bottom of runDailyTestSuite.sh to
+       invoke the new testcase(s) using the new tool:
+
+       py.test -v --junitxml results.xml ./test_example.py
+```
+
+### Test Output: formatting requirements
+The Jenkins automation tool that runs the test suite expects
+to receive xml output to display. For this reason, we execute
+tests in one of the following ways:
+
+Option 1. (Useful for any test language including bash, tool binaries, etc):
+   Invoke the test from within a python wrapper script, which allows
+   searching the stdout for a user-defined test result string.
+   Using the python wrapper makes it easy to provide the desired
+   junitxml output format. For example:
+
+```
+      py.test -v --junitxml results.xml ./test_example.py
+```
+
+Option 2. (Useful for GO tests):
+   Execute "go" tests, and pipe output through a tool such as
+   github.com/jstemmer/go-junit-report to convert to xml. e.g.:
+
+```
+      cd ../../tools/OTE
+      go get github.com/jstemmer/go-junit-report
+      go test -run ORD7 -v | go-junit-report >> results.xml
+```
