    [AMQP 1.0] small fixes to improve timer scalability

    This patch introduces the following tweaks to the timer
    implementation:

    Reduce the number of timers that need to be tracked by reducing the
    timer granularity to units of seconds.

    Decrease the default timeout values to further reduce the total number
    of tracked timers.

    Batch multiple expiring events that share the same deadline.

    Inline the timer comparison code in the main event loop.

    Avoid using an expensive comparison method in the heap sort by using
    an integer primitive instead.

    Use monotonic time instead of time.time()

    Log a warning when connected to a routable message bus

    Newton will be the first release of support for this new message bus
    technology. Make users aware that this feature is 'bleeding edge' and
    queuing is not supported in this release.

    Remove the max_send_retries option

    This option was added for feature parity with the rabbitmq driver.
    Since then the option was removed from rabbitmq. Since this option
    was never released we can simply remove it rather than deprecating it.

    Set the default link property to allow message acks

    Previously the default snd-settle-mode caused the sender to assume the
    message would not be acknowledged so the sender never waited for an
    acknowledgement. The 'mixed' setting allows the sender to request
    that the receiver acknowledges the message. The term 'mixed' comes
    from the AMQP 1.0 standard.

    [AMQP 1.0] Add configuration parameters for send message deadline

    This patch add driver configuration option parameters for oslo_messaging_amqp
    reply, send and notification timeout. These timeouts are used when the caller
    does not provide a timeout expiry.

    Re-factor the AMQP 1.0 addressing semantics

    This patch introduces a new routable addressing format. This new
    address format not only works with traditional broker-based messaging
    backends but can be used to optimally route messages across a mesh
    messaging topology. This new addressing format may be enabled either
    via configuration or by message bus identification.

    This patch moves all of the AMQP 1.0 addressing logic into a new
    Addresser class. This class is used to map an oslo.messaging Target
    address and notification flag into a corresponding AMQP 1.0
    message/subscription address based on the addressing mode. This hides
    the addressing details from the rest of the driver.

    For backward compatibility with previous releases the Addresser can be
    configured to automatically detect a non-routable messaging back end
    and fall back to using the legacy addressing scheme.

    The intention is to use routable addressing as the only form of
    addressing supported by the driver regardless of messaging back end.
    However before that can happen the legacy addressing must follow the
    standard deprecation process. Until then legacy addressing will
    remain available for backwards compatibility.

    Refactor link management to support link recovery

    This refactors the driver to process send/subscribe requests as they
    arrive from the application rather than blocking these requests until
    the reply link is activated. This allows recoverable failures
    occurring at the connection or link level to be applied to the sender
    retry count. This patch also implements link re-connect for
    subscriptions.

    These changes are required to support a brokerless routed mesh
    backend.
