Create a shared queue for QPID topic consumers

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.
