Long: `Command group used to interact with revision tags. Revision tags allow for the creation of mutable aliases
referring to control plane revisions for sidecar injection.

With revision tags, rather than relabeling a namespace from "istio.io/rev=revision-a" to "istio.io/rev=revision-b" to
change which control plane revision handles injection, it's possible to create a revision tag "prod" and label our
