Ditch microk8s plugin mayastor and install openEBS directory on k8s

Disabling the plugin didn't work, but thankfully removing the helm chart did just what I needed!

helm install openebs --namespace openebs openebs/openebs --create-namespace --set mayastor.csi.node.kubeletDir=/var/snap/microk8s/common/var/lib/kubelet/ --set engines.local.zfs.enabled=false --set lvm-localpv.lvmNode.kubeletDir=/var/snap/microk8s/common/var/lib/kubelet/

kubectl label node openebs.io/engine=mayastor
