Requested Update

Description

PR #659 introduced a new shared argument --log-level which sets the level in which we'll output information with a logger object. This argument is now working, however it's not easy to access the LOG attribute that will be shared amongst all command classes. Currently, the way to access LOG goes as such:

self.LOG = getattr(LOG, self.GEOIPS_ARGS.log_level)
self.LOG("LOG LEVEL = {self.GEOIPS_ARGS.log_level}")

This sets the logger object at the correct log level, but this does not actually share the same logger object with all command classes. We need to figure out a method to parse --log-level before all command classes are initialized, so they can all inherit the same logger object from GeoipsCommand.

Background and Motivation

This comes from this comment on PR #659.
