Public bug reported:
In case network failover is turned on, remove_network_from_dhcp_agent method is
a matter of concurrent execution by different neutron servers.
It then may throw unexpected DB exception, breaking network failover looping
call.
Neet to make both remove_network_from_dhcp_agent and
remove_networks_from_down_agents more robust by catching broader
exception in the loop, and using safe DB delete method.
