* Added code to support entity and domain filters in the config for splunk component, and the code to enforce the filter.
* * Moved code for posting splunk request to separate function, primarily to more easily write a test case where I can mock the point where the post would occur and validate that filtering is working correctly.
* Test cases created for full config check and to test the filtering
* Correcting static check errors/issues
* Correcting flake8 static check issue (introduced when addressing prior static check issues)
* Removing unused parameter to setup function - cleanup from reviewer request.
