    Bulk up port status updating in ML2 RPC

    This eliminates the last of the bottlenecks in
    get_devices_details_list_and_failed_devices by making the status
    updates use a bulk data retrieval as well.

    The last remaining thing that will impact performance is the status
    update back to ACTIVE on removal of the provisioning blocks. However,
    that will require a much larger refactor since it is callback driven
    at the individual port level.

    Elimination of the L2pop driver will ultimately solve this completely
    since we won't need to cycle the port status anymore on every single
    agent restart.
