This commit updates external-snapshotter version to v4.0.0 which supports snapshots v1. Rook now defaults to enabling RBD and CephFS snapshotter for K8s >= v1.17 and disabling it for K8s <= v1.16. Supporting changes in documents and examples yaml files are made. Signed-off-by: Rakshith R <rar@redhat.com>
