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 Signed-off-by: Humble Chirammal <hchiramm@redhat.com>
