Code Issues Proposed changes

Improve no-auth path

Browse Source 
The commands that do not require authentication sometimes still need
to call ClientManager.is_network_endpoint_enabled() to see if Neutron
is available.  Optimize the paths a bit to skip auth when it is not
necessary; the upshot is Neutron will be assumed in these cases now.

This gets a LOT cleaner when it appears is a future osc-lib.
