Add functionality to skip correct based on run type

Description

• Added key correct/skip-run-types to webservice config, which is a list of strings
• Added function check_run_type_skip which queries mymdc with a run ID to get the run type, and checks if the type is in the list, if it is it returns True, else False
• Added Errors.RUN_SKIPPED to messages.py, to be returned if a run is skipped
• Added call to above function to handle_correct, which will log RUN_SKIPPED, send the message to mymdc, and then exit the correct function early, if a run type is marked as to be skipped

@schmidtp do you know if you'll have the run type(s) to be skipped soon? If not then I can just mock something in for the tests, instead of testing with the actual value in the config
