    Capture port deleted event associated to HM ServiceMonitor

    When the port associated to a VM is deleted, if a ServiceMonitor
    row is associated to that port an OVN SB event is triggered
    in order to communicate that the ServiceMonitor entry is been
    deleted. That event would allow us to update the status of
    member/pool/LB according to the event.

    This patch suscribes the driver agent to the DELETE events
    for table ServiceMonitor on the OVN SB DB in order to
    update the operating_status when the VM port is deleted.
