Description of problem: When deploying Azure CSI driver on ASH, we see this error: Warning Failed 5m43s (x26720 over 4d2h) kubelet (combined from similar events): Error: container create failed: time="2021-08-10T15:41:20Z" level=error msg="container_linux.go:380: starting container process caused: process_linux.go:545: container init caused: rootfs_linux.go:76: mounting \"/var/lib/kubelet/pods/9b6be4b7-86c2-45e1-a6ce-032faf62a332/volume-subpaths/azure-cfg/csi-driver/3\" to rootfs at \"/etc/kubernetes/azurestackcloud.json\" caused: open /var/lib/containers/storage/overlay/ed6766de84eff62c52dc3446d5e4b77e2ca9ff2232c6357bff773ff3cd0e0a22/merged/etc/kubernetes/azurestackcloud.json: read-only file system" Seems like this happens because we try to mount azurestackcloud.json file to /etc/kubernetes which is read-only: https://github.com/openshift/azure-disk-csi-driver-operator/blob/master/assets/controller.yaml#L74
