Auto scale coredns pods#514

Conversation
Currently k8s canonical only deploys 1 coredns and not scaled. Bug raised on canonical k8s [1]. Add a workaround in sunbeam until [1] is fixed. Logic is to use hpa to scale between 1 to 5 pods based on 80% cpu utilization. Also increase the resource limits and requests for coredns pod. Increase cpu requests/limits to 500m, memory requests/limits to 128Mi [1] canonical/k8s-operator#504 Related-Bug: https://bugs.launchpad.net/snap-openstack/+bug/2112396
