Public bug reported:
When an HA router initialization fails, it can lead to the following
exception:
ERROR neutron.agent.l3.ha_router [-] Unable to process HA router
59fad7c2-d393-464f-820b-334927047e64 without HA port

TRACE neutron.agent.l3.agent AttributeError: 'HaRouter' object has no attribute
'process_monitor'
The problem is that self.process_monitor is added in
RouterInfo.initialize(), but that isn't called after we verify an
ha_port exists in HaRouter.initialize().
Adding 'self.process_monitor = None' in RouterInfo.__init__ should fix
the problem.
