Return logger name

[djarbz]

Is your feature request related to a problem? Please describe.
I am writing an application that overall should have a user specified log level, ie INFO.
But they can overwrite the log level for certain "actions" that would be handled on a case by case basis.
Since we are unable to change the log level of a cloned logger, I am instantiating a new logger set to the DEBUG level.
Currently, this new logger does not have the inherited name for the existing logger.
I would like a function such as zapLog.GetName() that would return a string of the current log name that I can then pass on to the new logger.

Is this a breaking change?
I do not believe this would be a breaking change as it would add a function to the current interface.

It seems reasonable to add Name() string to *Logger that exposes the name.
