    [Kubernetes] Bunch of issues regarding scaling was fixed

    1. There was scaleGatewayUp but no Down action
    2. Gracefully remove node from etcd upon down-scale of nodes/gateways
    3. Log to user which gateways were created/deleted
    4. Deployment either hanged or worked incorrectly when downscaling and then
         upscaling something again

    Also sets minimum gateway node count to 1 until gateway-less mode be fully
    functional again
