    Listen alternative topic for state reports

    Recently Neutron agents have been changed to use topics.REPORTS
    for state reports. [1] Update our plugin to accept the topic as well.

    In case of MidoNet, this topic is used to accept messages from
    Neutron dhcp and metadata agents. While MidoNet v2015.09 and
    later will have an alternative metadata proxy [2] which doesn't use
    these agents, it's nice to maintain the old way at least for
    a cycle. And v1 plugin needs this anyway.
