Split config.py into multiple files

[gtsiam]

Proposed change

• I got tired of scrolling through config.py so I split it up into multiple, more manageable, files.
• Fixed FrigateConfig.install() being called too late to apply logging configuration to FrigateConfig validation logic.
• Replaced all instances of logging.warn with logging.warning, since warn is deprecated.

Okay, last force-push. This is final. Just a few things I noticed right after I made the PR. Classic.
