If True will enable ACTIVE/PASSIVE HA mode for neutron agents using
Pacemaker and Corosync. This is intended for < Juno which natively
supports HA in Neutron itself.
If True will enable Pacemaker to monitor the neutron-ha-monitor daemon
on every neutron-gateway unit, which detects neutron agents status and
reschedule resources hosting on failed agents, detects local errors and
release resources when network is unreachable or do neccessary recover
tasks. This feature targets to < Juno which doesn't natively support HA
in Neutron itself.
