Rename client/common_lib/logging.py to client/common_lib/log.py in order to be able to use the standard python logging module

Python has a standard module used to perform logging operations
(http://docs.python.org/lib/module-logging.html) that could be used
inside autotest, however we have a common_lib module named logging as
well, that makes difficult to import the python logging module in all
other parts of autotest (including tests). 

So this patch basically renames logging to log and fixes all references
to it. All the files touched were pylinted and basic sanity testing was
made (running autotest with different control files).

About the risks, in my opinion it's worth the effort, since we gain the
ability to use a powerful logging library, that would help us to
implement a better logging system inside all autotest modules.

Risk: Medium/High - Even though care was taken to ensure all references
to logging were changed, it touches a fair bit of the code and something
might have passed unaudited.

Visibility: Low - Should be invisible for all users, and developers must
just remember that now logging is called log.
