Summary

NIFI-13950 - NiFi CLI - add commands to list branch, bucket, flows, versions through NiFi for Registry Clients

Currently, the CLI only provides access to branches / buckets / flows and versions via the use of cli.sh registry ... which only works when using the NiFi Registry.

Now that Registry Client is an extension point and that we have additional implementations, we should provide CLI commands to provide read-only access through a given registry client for listing branches / buckets / flows and versions. This will help users when they want to import a given flow with cli.sh nifi pg-import .... In particular when it relates to versions because, when using a GitHub Registry Client, the version is a commit ID and it might not always be easy to retrieve / provide.
