    Fix "loss of redundancy" alarm in SX subcloud

    Service group distributed-cloud-services loss of redundancy alarm
    is raised in AIO-SX subclouds. This is due to the redundancy model
    expects 1 standby member but no standby members available.

    This update changes the distributed-cloud-service redundancy model
    to no standby member in AIO-DX subclouds
