    Change the qpid_heartbeat default to 60 seconds.

    The heartbeat option enables sending a message at the AMQP layer at a
    regular interval. This helps ensure that the connection is still up and
    working. Once a failure is detected, a reconnection can be attempted.

    The default for qpid_heartbeat was previously 5 seconds. This is pretty
    aggressive and can lead to invalid timeouts occuring. An example is the
    nova-compute service. It may block in native code (such as libvirt)
    under normal circumstances. When this happens, other greenthreads (such
    as the one responsible for sending the heartbeat) can not be scheduled.
    This patch makes the default a less aggressive 1 minute.

    Fix bug 1050661.
