It would be nice to group rpkg commands by different kinds of usage. Basically, they can be divided into these categories,

• basic operation on package, e.g. lint, import, clone, pull, clog, verrel

• local package build, e.g. local, compile, install, mock, mock-config

• remote package build in either Koji or Copr, e.g. build, scratch-build, copr-build, container-build

• sources management, e.g. upload, new-sources, sources

fedpkg and rhpkg could be able to define their own group. For example, fedpkg may have a group containing Bodhi related commands update and the override.

It may be necessary to change `register_* methods in fedpkg and rhpkg accordingly.
