Fix devstack with linuxbridge without l3 agent

Browse Source 
The linuxbridge agent for Neutron expects that the public bridge will
already be created by the time it starts. On devstack, this only occurs
as part of the l3 agent configuration. If a compute node doesn't have an
l3 agent and is using a linuxbridge agent, then br-ex won't be created
and the process will not be able to start (causing stack.sh to fail).

This causes the gate-grenade-dsvm-neutron-linuxbridge-multinode-nv gate
to fail. To avoid the issue, skip the bridge mappings setup unless L3 is
configured. This is done in a backward compatible fashion: if localrc
uses the old q-l3 tags, the is_service_enabled neutron-l3 would not be
able to succeed.

Closes-Bug: #1643562
