    Create a shared queue for QPID topic consumers

    Fixes bug 1257293

    This is a cherrypick of oslo-incubator:
    e355fa3a9f49ff524ce98d1263a784b5a7929dfb

    From the oslo-incubator commit:
    When multiple RPC servers (consumers) are subscribed to the same RPC
    topic, a single RPC request to that topic should be received by only
    one of the consumers. A bug in the QPID driver caused every consumer
    to receive a copy of the RPC request. This bug affects only Topology
    version 2. This patch will cause a single queue to be created for
    each topic, and shared among all consumers of that topic. This
    results in each RPC request being received by only one consumer,
    in turn across all the competing consumers.
