Remove an unused imported module

The urlparse module is imported in neutronclient/client.py but not used, so we
can safely remove it.

Fix description of ListSubnet

The help texts for both "neutron net-list" and "neutron subnet-list"
give the same text "List networks that belong to a given tenant."

Fix it so that subnet-list output the proper "subnet"

setup logger name of NeutronCommand automatically

It is a common pattern to add
class XXXCommand(NeutronCommand):
    log = logging.getLogger(__name__ + '.<command name>').
So introduce a metaclass to do that automatically in order to simplify
the code a bit.

Fixes bug #1258028
