Bug description:
  In attempting to reconnect to an AMQP server when a communication
  failure occurs, both the qpid and rabbit drivers target the configured
  servers in the order in which they were provided.  If a connection to
  the first server had failed, the subsequent reconnection attempt would
  be made to that same server instead of trying one that had not yet
  failed.  This could increase the time to failover to a working server.

  A plausible workaround for qpid would be to decrease the value for
  qpid_timeout, but since the problem only occurs if the failed server
  is the first configured, the results of the workaround would depend on
  the order that the failed server appears in the configuration.
