Title:
  Sometimes L3 rpc update operations produce deadlock errors

Status in neutron:
  Fix Released

Bug description:
  When DB backend works in a multimaster mode and L3 agents are setting up floating ips and routers, they often produce
  Deadlock errors when changing floating IP or router statuses.

  Need to add db_retry decorator to corresponding rpc handlers.
