    Tune _get_candidates for faster scheduling in dvr

    Right now we have seen some performance issues when
    dvr routers are scheduled on multiple compute nodes
    with thousands of VMs on the routed subnets.

    The _get_candidates call get_l3_agent_candidates with
    a complete list of agents irrespective of the routers
    already hosted on the agents or not.

    So this fix will reduce the amount of iterations that
    get_l3_agent_candidates need to process for all the
    agents and would increase the control plane performance.

    Closes-Bug: #1513678
