Public bug reported:

DVR routers are not created on a compute node that is running L3 agent
in "dvr" mode.

This might have been introduced by the latest patch that changed the scheduling behavior.
https://review.openstack.org/#/c/254837/

Steps to reproduce:

1. Stack up two nodes. ( dvr_snat node) and (dvr node)
2. Create a Network
3. Create a Subnet
4. Create a Router
5. Add Subnet to the Router
6. Create a VM on the "dvr_snat" node.
Everything works fine here. We can see the router-namespace, snat-namespace and the dhcp-namespace.

7. Now Create a VM and force the VM to be created on the second node ( dvr node).
  - nova boot --flavor xyz --image abc --net net-id yyy-id --availability-zone nova:dvr-node myinstance2

Now see the image is created in the second node.
But the router namespace is missing in the second node.

The router is scheduled to the dvr-snat node, but not to the compute
node.
