Debug messages appeaering with 0.5.2 -> 0.6.0 update

Seems requests-cache is using root logger and prints debug info with logging.info, should use logging.debug at least:

$ ./plex_trakt_sync.sh cache
INFO: Patching requests.Session with class: type
INFO: Initializing backend: sqlite
INFO: Initializing DbPickleDict with serializer: <class 'module'>
INFO: Using a secret key to sign cached items is recommended for this backend
INFO: Initializing DbDict with serializer: <class 'module'>

seems current workaround is to limit this module logging:

# somewhere in application startup
logging.getLogger('requests_cache').setLevel(logging.WARNING)

@JWCook in that application trakt and plex debug entries are also logged (on purpose) to application file log (not terminal).

the only breaking change was that 0.5.x used no logging and 0.6.0 used info log level, so these end up in the console (terminal).

but I think you changed info -> debug. I have not verified were all log calls changed or just a few.
