Adds a `-verify-config` command line argument, that when specified will verify the Checks and CheckOptions fields in the config files:

- A warning will be raised for any check that glob that doesn't correspond to a registered check, a suggestion will also be emitted for close misses.
- A warning will be raised for any check glob that doesn't match any registered check.
- A warning will be raised for any CheckOption that isn't read by any registered check, a suggestion will also be emitted for close misses.

This can be useful if debuging why a certain check isn't enabled, or the options are being handled as you expect them to be.
