Improve bw_usage_update() performance
Fixes bug 1036084
bw_usage_update() most commonly updates rows vs creates rows. New rows
are only created on the 1st bandwidth update for an instance or when
the audit period rolls over. This cuts down DB queries to 1 for the
'update' case.
Added bonus:
Remove unused 'import inspect' in compute manager.
