    Silence amqp heartbeat warning

    When the nova api is executing under uWSGI or MOD_WSGI
    the lifetime of the amqp heartbeat thread is controlled
    by the wsgi server. As a result when the nova api is run
    in this configuration we expect that the heartbeat thread
    will be suspended and heartbeats will be missed when the wsgi
    server suspends execution of the wsgi application.

    This change adds a python logging filter to suppress
    the reporting of heartbeat warnings as this behavior is
    expected. Since the operator cannot do anything to address
    the issue the warning is just noise and many operators
    and customers find it to be off-putting.
