Remove qpid port and authentication details

Port 5672 is the default qpid port, and therefore does not need to be
specified (it is also inconsistent with previous qpid configuration
steps, which do not specify a port).  Additionally, no authentication
was configured for qpid in the documentation, so the authentication
details should be removed.
