this follows the pattern in ceph-disk. this enables us to run
ceph-detect-init/run-tox.sh from the ${CMAKE_BINARY_DIRECTORY}
as well.

please note "make test" is used by cmake to run tests, so we cannot just
repurpose it to *build* them.

* AddCephTest.cmake: depends on "tests"
* CMakeLists.txt: let "check" depend on "tests"
* src/CMakeLists.txt: update the run-tox tests
* run-make-check.sh: use "make tests" and "ctest" instead of "make check"
* ceph-detect-init/CMakeLists.txt: let "tests" depend on
    "ceph-detect-init"
* ceph-disk/CMakeLists.txt: let "tests" depend on "ceph-disk"

run-tox-ceph-disk and run-tox-ceph-detect-init are already added as
test, so "ctest" and "make {test,check}" will run them without extra
settings.

two tests timesout for unknown reasons, so label them with
"Racing" and "LongRunning" labels.

this is a workaround of the timeout found in jenkins. currently three
tests are found timeout, and they are labeld with "Racing" and
"LongRunning". so, to workaround this issue, we run the tests in two
phases:

1. run the racing tests with -j1
2. run the non-racing tests with -jN

if we all all tests with -j1, the total test time is 2683.57 sec

as ceph_crypt.cc is using the symbols in it, and libcommon contains
ceph_crypt.cc.

they are included by rgw_a as well. and ceph_rgw_jsonparser is linked
against rgw_a.

on older versions of pip, this option is not supported, and
--disable-pip-version-check is implied with --no-index. so no need to
use them when --no-index is passed to pip.

this helps us to identify test hang.
