    Sync COMPUTE_STATUS_DISABLED from API

    This adds the os-services API change which will
    call the compute service when the service's disabled
    value changes to sync the COMPUTE_STATUS_DISABLED trait
    on the compute node resource providers managed by the
    updated compute service.

    If the compute service is down or not yet upgraded to
    the service version from change
    Ia95de2f23f12b002b2189c9294ec190569a628ab then the
    API will not call the service. In this case the change
    from I3005b46221ac3c0e559e1072131a7e4846c9867c will
    sync the trait when the compute service is restarted.

    Since the compute service could be running the ironic
    driver and managing hundreds or over 1000 compute nodes,
    the set_host_enabled RPC call now uses the long_rpc_timeout
    configuration option.

    A functional test is added which covers the 2.53+
    PUT /os-services/{service_id} API and pre-2.53 os-services
    APIs for enabling/disabling and forcing down a service.
    The functional test also covers the sync-on-restart behavior
    from change I3005b46221ac3c0e559e1072131a7e4846c9867c.
    The scheduler pre-filter added in change
    I317cabbe49a337848325f96df79d478fd65811d9 is also tested
    as part of the functional test.
