    Clean duplicated QoS bandwidth related methods in ovs_lib module

    This patch also some helper methods used in the
    minimum bandwidth qos methods as it seems that we had things almost
    duplicated in methods like _find/update/delete_{qos,queue} and
    find/update/delete_{qos,queue}.

    It also moves functional tests for the ingress bandwidth limit rules
    methods to more appropriate module.
