Add h2o version with cluster name and disable connect button if not supported
When connecting to H2O cloud, get H2O version and show next to cloud name. If H2o Version is less then 22.214.171.124 (or considered to be unsupported) do not enabled connect button instead grey it out. Also show a message that - "Given h2o server version is not supported, please use H2O version 126.96.36.199 or above to use with Steam"
This way we will block unsupported cluster version problem where NPE happens when loading models from an upsupported H2O cluster.
