* `upgrade apply` will try to make the locally configured and actual version in the cluster match by appling necessary upgrades. * Skip image or kubernetes upgrades if one is already in progress. * Skip downgrades/equal-as-running versions * Move NodeVersionResourceName constant from operators to internal as its needed in the CLI.
