Generalize remote license checker (#32971)
Machine learning has baked a remote license checker for use in checking license compatibility of a remote license. This remote license checker has general usage for any feature that relies on a remote cluster. For example, cross-cluster replication will pull changes from a remote cluster and require that the local and remote clusters have platinum licenses. This commit generalizes the remote cluster license check for use in cross-cluster replication.
