Moved full dump of requests+responses+events to log debug level.

Messages can be quite big and verbose, and they can anyway be subscribed
over Websockets.

Full dumps are anyway enabled when Platypush is started in verbose mode.

This commit replaces the dumps on INFO level with a quick summary
containing the message ID, request/event type and response time.
