As a result bumping the major version * bumping node-red docker image to the latest stable version * using volumeClaimTemplates for statefulSet Signed-off-by: Jeff Billimek <jeff@billimek.com> * using Parallel podManagementPolicy Signed-off-by: Jeff Billimek <jeff@billimek.com> * revert to Deployment and leverage strategy types Signed-off-by: Jeff Billimek <jeff@billimek.com> * hard-code replica count Signed-off-by: Jeff Billimek <jeff@billimek.com>
