Reduce log noise by lowering log levels

The current implementation spits out a large stack trace into the logs when receiving any http status code other than 200 from external services. This should be reduced to allow for easier debugging on prod and staging, while keeping the stack traces available in DEBUG mode.

Something like this should work:

[WARN] FDNDB-API - No org contact results for user: {user}, code {code}. Enable DEBUG logging for more detailed messaging
[DEBUG] FDNDB-API - No org contact results for user: {user}, code {code}: {exceptionType} {stackTrace}
