fix(LoginClassifier): Adjust log levels / reduce logging noise

[joshtrichards]

While #152 addressed rate limiting notifications to users, we still have some logging outside of there that isn't covered.

• Adjusts log levels (Warning -> a mixture of Debug and Info) of the two main messages that aren't rate limited
• Adjusts log levels of the already rate limited messages to Info level (from Warning) to be more consistent with Brute Force Protection log levels

This cuts down on the log noise from "Detected a login from a suspicious login..."

All logs remain available at the appropriate log levels if desired.

Fixes #303

To me this looks more like fighting the symptoms rather than fixing the actual issue.
