Neutron HA nodeset of 3 controllers and 2 computes

The neutron tempest migrated plugin has tests that soft/hard shutdown
services/nodes and expect HA setup to handle it.

Therefore this change adds a devstack OVS HA gate job to notice such
tests work properly, and any HA checks related code isn't broken.
