Bug Description
At scale when we have 100s of compute Node and 1000s of VM in networks that are routed by Distributed Virtual Router, we are seeing a control plane performance issue.
It takes a while for all the routers to be schedule in the Nodes.
The _schedule_router calls _get_candidates, and it internally calls get_l3_
This might be taking lot more time.
So we need to figure out the issue and reduce the time taken for the scheduling.
