    Kombu: make reply and fanout queues expire instead of auto-delete

    Right now fanout and reply queues are unconditionally created with
    auto-delete flag which causes a number of problems listed in bug
    1495568. Replacing auto-delete with queue expiration with some sane
    timeout should fix all these issues at once.

    Another problem being fixed is that auto-delete flag does not causes
    the queue to be deleted if it never had consumers. An orphaned fanout
    queue might appear that way and it will grow indefinitely until
    somebody manually removes it. See bug 1515278 for details.

    A new rabbit_transient_queues_ttl config parameter is introduced which
    configures the TTL for reply and fanout queues. It is a positive
    integer representing timeout in seconds. By default it is set to 10
    minutes. That should be enough for application to reconnect or
    for server to send reply to client which already died. At the same
    time, it seems that not so many messages could be accumulated in
    fanout queues during that time.

    DocImpact
    With this change RabbitMQ driver defines reply and fanout queues
    differently comparing with the previous release: now they are defined
    with queue TTL (https://www.rabbitmq.com/ttl.html#queue-ttl) instead
    of auto-delete flag. That helps avoid a number of issues, see commit
    description for details. A new rabbit_transient_queues_ttl parameter
    is defined which controls the TTL value. It is set to 10 minutes by
    default. The change does not affect upgrade in any way.

Jorge,

I've uploaded this to wily and it will require SRU team review before it gets into wily-proposed. Can you update the bug description with the standard SRU sections? [Impact], [Test Case], and [Regression Potential].

Thanks,
Corey

@niedbalski FYI, tempest results from wily-liberty-proposed and trusty-liberty staging are consistent with wily-liberty (distro) and trusty-liberty (uca updates). ie. No new failures. Now that it has been promoted to trusty-liberty-proposed, we will need to re-test there. There is typically a 1-wk bake period for proposed cloud archive pockets.

Hi Chris and James,

python-oslo.messaging 2.5.0-1ubuntu2 has been verified on wily-proposed and trusty-liberty-proposed.

Thanks,
Corey
