venkata anil 9ab1ad1433 Call update_all_ha_network_port_statuses on agent start 
As explained in bug [1] when l3 agent fails to report state to the
server, its state is set to AGENT_REVIVED, triggering
fetch_and_sync_all_routers, which will set all its HA network ports
to DOWN, resulting in
1) ovs agent rewiring these ports and setting status to ACTIVE
2) when these ports are active, server sends router update to l3 agent
As server, ovs and l3 agents are busy with this processing, l3 agent
may fail again reporting state, repeating this process.

As l3 agent is repeatedly processing same routers, SIGHUPs are
frequently sent to keepalived, resulting in multiple masters.

To fix this, we call update_all_ha_network_port_statuses in l3 agent
start instead of calling from fetch_and_sync_all_routers.
