Title:
  DVR: should not remove routers form down l3 agents on compute nodes

Status in neutron:
  Fix Released

Bug description:
  Currently If 'dvr' l3 agent on a compute node goes down, routers are
  removed from it; then when agent is up again routers are not added
  back - so VMs on that compute node lose all routing.

  Scheduling/unscheduling of DVR routers to the l3 agent in 'dvr' mode
  running on a compute node is done according to dvr serviced ports
  created/deleted on that compute node. It doesn't make sense to
  reschedule router from l3 agent on compute node even if it's down - no
  other l3 agent can handle VMs running on that compute node.
