Filter HA routers without HA interface and state
This patch adjusts the sync method to exclude any HA
routers from the response that are missing necessary
HA fields (the HA interface and the HA state).
This prevents the agent from every receiving a partially
formed router.

Title:
HA router can not be deleted in L3 agent after race between HA router
creating and deleting
Status in neutron:
Fix Released
Bug description:
HA router can not be deleted in L3 agent after race between HA router
creating and deleting
Exception:
1. Unable to process HA router %s without HA port (HA router initialize)
2. AttributeError: 'NoneType' object has no attribute 'config' (HA
router deleting procedure)
With the newest neutron code, I find a infinite loop in _safe_router_removed.
Consider a HA router without HA port was placed in the l3 agent,
usually because of the race condition.
Infinite loop steps:
1. a HA router deleting RPC comes
2. l3 agent remove it
3. the RouterInfo will delete its the router
namespace(self.router_namespace.delete())
4. the HaRouter, ha_router.delete(), where the AttributeError: 'NoneType' or
some error will be raised.
5. _safe_router_removed return False
6. self._resync_router(update)
7. the router namespace is not existed, RuntimeError raised, go to 5,
infinite loop 5 - 7
