Rabi Mishra 25becbcbf4 Add config entries to skip integration tests
This adds options to skip scenario and functional tests.
You can either skip the complete set of tests or list of specific
tests.

Following new config options are added:

`skip_scenario_tests` -  Skip all scenario tests
`skip_functional_tests` - Skip all functional tests
`skip_functional_test_list` - List of functional tests to skip
`skip_scenario_test_list` - List of scenario tests to skip
`skip_test_stack_action_list` - List of actions in tests to skip
