[neutron-api] remove leader_only for sb connection

Browse Source 
The maintenance worker from the neutron-api uses a southbound
connection. Since the southbound does not use any locking and all the
ovsdb locking is used for the northbound this changes should not have a
big impact.

This commit removes the leader_only flag for the maintenance worker.
This should also enable the neutron api to connect to relays instead of only
the sb directly.

[`bug 2022914 <https://bugs.launchpad.net/neutron/+bug/2022914>`_]
Neutron-API supports using relays as the southbound connection in a
ML2/OVN setup. Before the maintenance worker of the API required a
leader_only connection, which was removed.
