    Prevent deletion of a subnet with lbaas v1 pool

    When using LBaaS and trying to delete a subnet, neutron has no way of
    knowing if the subnet is associated to some pool. As a result, the
    subnet is deleted but the pool remains associated to the (now
    nonexistent) subnet_id. This patch adds a check in LBaaS side to
    prevent such a case, using the callbacks system.
