Public bug reported:

Scenario
 - have vm running on a subnet not connected to a router
 - create router with gateway:
   neutron router-create router1 -- --external-gateway-info type=dict network_id=<uuid>
 - connect subnet to a router
 - check l3 agents hosting router
In this case only csnat portion of the router will be scheduled to dvr_snat l3 agent on network node.
Router will not be scheduled to a dvr l3 agent on compute node hosting VM, as well as to other l3 agents on networks nodes hosting dhcp ports.

This is a regression from commit
3794b4a83e68041e24b715135f0ccf09a5631178 where scheduler will return
once snat portion is scheduled.
