[bug] unify logging style using class attr

I changed most of the logger statements to use a class attribute, in
this way it's easier to identify which class it's logging them.

in some cases I leave a module-level logger, when we're either using
functions or when the module it's too small.

at the same time I did a general review and cleanup of the logging
statements.
