    Disable [oslo_messaging_rabbit] heartbeat_in_pthread

    Default value of this option was updated during Wallaby cycle[1] but
    the new default(true) is causing problems with non-wsgi services like
    nova-compute and we've learned these services are not able to behave
    properly in some cases(when starting up, reconnecting to MQ, etc)[2].

    This change overrides the parameter to use the old default value until
    the problem is fixed in oslo.messaging(or in any other layers).
