Ability to display debug print from only certain modules

[tysmith]

If DEBUG=1 is set we get the output from all modules and some are very verbose (avalanche). Having more control over which modules output debug info would be helpful.

I changed the default logging verbosity to INFO for avalanche because it is super verbose. In general, the adapter should probably tweak the loggers used by its imports if they are too noisy.
