Stan Lagun 9715d5e3e7 [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
