Use argparse only if name is main, call main with args dict

Description

Working on the tests, mildly annoyed by way the webservice uses argparse and how it's started so I changed it a bit:

• Adjusted some of the command line argument names and variable names so that they match
• Argparse setup is only done if webservice.py is called by python (if __name__ == "__main__")
• Changed the main function to take in keyword arguments
• Splat argparse args dict into main if called by python

NOTE: --logging has changed to --log-level

How Has This Been Tested?

Not at all

Called it manually with some print stuff:

❯ python3 ./webservice/webservice.py --log-level DEBUG
{'config_file': './webservice.yaml', 'mode': 'sim', 'log_file': './web.log', 'log_level': 'DEBUG'}
./webservice.yaml sim ./web.log DEBUG

Seems to work.
