[Python] Adjust logging levels in Python controller

Use global loggers per-module which is more Pythonic and avoids
unnecessary logger instances. Also use the module name as the logger
name consistently.

Avoid using the warning level for messages which are really only
informational. Also lower the log level of storage messages to debug,
as they are really not that important. Drop some unnecessary logs
like on every storage commit.
