Add function for running all test in $TEST_SET.

[zmiklank]

The function could be then called to run every application container test suite.

Also, @phracek, is the ct_run_test_list function from test-lib.sh still valid? Seems, it does similar work.

ct_run_test_list

It could be enhanced. I totally agree to have only one function. It is not used at all. See https://github.com/search?q=org%3Asclorg+ct_run_test_list&type=code

[zmiklank]

I removed the ct_run_test_list function.

I updated the ct_run_tests_from_testset function, so it works with global TESTSUITE_RESULT.

[zmiklank]

I added a _ct_check_testcase_result function to test-lib.sh.
