basic support for inheritance of CK entries

• added support for basic inheritance in CK entries via "_base_entry" key. Useful to simplify program, package and soft modules. See ticket #143.
• added program.template, soft.template and package.template modules to describe base entries for inheritance.

added missing requirements.txt to the main distro

V2.0.9

simplifying setup.py

• added requirements.txt file with pyyaml
• simplified setup.py script
• added incubating projects to simplify CK

fixed a major bug in the installation system

V2.0.10

fixing typos

aggregated fixes and improvements

  • added more tests to catch bugs in program workflows
  • fixed a new bug in the program workflow
  • updated docs

• V2.0.6

  • improved module:program meta to be able to use global CMD run_time parameters for all command lines (useful to run different MLPerf scenarios with similar run time parameters)

• V2.0.5

  • added possibility to pull CK repositories from different GitHub organizations as follows: "ck pull repo:{organization}@{repo}"
  • removed old and not used meta "backup_data_uid" and "data_name" from program entries

• V2.0.4

  • fixed modules mlperf.inference and mlperf.mobilenets to cache results in local:tmp:{some cache}

• V2.0.3

  • fixed a minor bug in module:program

• V2.0.2

  • Added --print_skip_stats to "ck benchmark program" to reduce output for MLPerf benchmarks
  • Added --print_files to "ck benchmark program" to print multiple files after MLPerf benchmarking
  • Removed several data zips that are not required for the releases

improving script generation and support for Python 3.8+

• Updated deprecated function in web server to support Python 3.8+
• We now use Python to generate ck and ck.bat scripts! If you install CK for different python versions, you can use a specific one as follows:

python3.7 -m ck version

Apache 2.0 license

• We now use Apache 2.0 license based on the feedback from the majority of users
• The code did not change from the last version 1.55.17.
• We plan to focus on incubating projects (see "incubator" directory) to redesign CK and make it simpler, faster and more Pythonic - we plan to use version 3.x for the new design.

fixed major bug and added MLPerf tests

• fixed a bug in module:env.
• added more MLPerf tests from https://github.com/ctuning/ck-ml to find above bug.
• added detection of packages with problems to print notes about how to solve them (useful for ImageNet 2012 packages where direct download is no longer available).

added LICENSE.third-party.txt and module:docs

• added module:docs to be more compatible with standard repos
• added LICENSE.third-party.txt

improved error reporting

• improved error reporting in packages and programs
• print "Enter -1 to use CK packages" when detecting soft to install CK packages instead of detecting already installed software
