Remove logging debug of loaded modules

[kkwaiser]

Hi there,

Would you be willing to remove this debug statement from the init.py file? It leads to excessive logging output. In my case, it is printing the name of ~1800 modules and really crowding out more valuable debug statements. Thanks!

matplotlib/lib/matplotlib/__init__.py

Line 1445 in 98115e9

_log.debug('loaded modules: %s', list(sys.modules))

A version of that log statement has been there from 2004 so I am wary of removing it. This also seems like it is problem that can / should be solved on the consumer side.

On the other hand, I am not sure what the actual value of that log is (as it is not specific to Matplotlib) and came in the svn days via c3b1103 with the comment "add zorder" which seems unrelated. I also think it got swept up as part of the mass move from our custom logging -> standard logging without a lot of consideration.

In the process of writing this I managed to talk myself from be weakly against removing it to being weakly in favor of removing it.

Because it is a change of a long standing behavior it will need a note in the API changes, but no deprecation period. Labeling as good first issue is it is removing 1 line + writing a sentence documenting that it was removed.
