`logger_kwargs` isn't used in one branch of the pipeline manager setup

[vreuter]

In the pipeline manager constructor, it looks like logger_kwargs isn't used when args is non-empty or non-null. Is this intended? There's also no docstring for logger_kwargs, where it could be noted if this is indeed intended behavior, or at least describing what these values are to be used for.

Possibly related to #210

Perhaps **logger_kwargs should be passed to logmuse.init_logger?

^^ controlling, perhaps, for possibility of collision w/ level (i.e., either remove level from the keyword args mapping if it's there--noting difference w/ DEBUG if that's the case--or not passing level='DEBUG' if level's already in the kwargs mapping.

Hmm, I never understood what logmuse was doing with init_logger and I still don't :).

you taught me everything I know about the logging package
