deploy: adjust minikube deployment for RWOP support

The ReadWriteOncePod feature gate need to be enabled only when we
are operating on kube 1.22 or above cluster. This commit adds the
logic to parse the kubernetes cluster at time of minikube deployment
and if it is above v1.22, enable the RWOP feature gate
