To chase down a set of tests that were failing together, we wanted to run
deeper trees of tests. We changed the behavior of the --pkg argument to
runtests.py so it runs tests under a package and its subpackages, instead
of for a single node.
It gave us more flexibility in what tests to run. This also includes the
--exclude option.
To run tests for a single node, ".tests" can be appended to the package path.
Tira & George.
1. The user will specify the tablespace path in test_config.json.in
2. If tablespace path not found, skip the test cases for that server(Only tablespace test cases)
3. Add the skipped test summary in the test result. (Now it's showing on console + in log file, but need to update in a final enhanced test summary report. Which is research point we will work on that after finishing all nodes API test cases)
4. Removed the test_ prefix from the values in the config files.
5. Add tablespace and roles tests
