An HA port needs to point to the correct host (where the master router
is running) in order for L2Population to work.
Hence, this patch introduces two fixes:
* When a port owned by an HA router is up we make sure it points to the
right node where the master is running, or a random node if there is
no master yet (This corner case is fixed by the 2nd bullet point).
* When a L3 agent reports it's hosting a master, we need to update the
port binding to the host the master is now running on. This fixes
both routers with no elected master (Yet) and failovers.
