Removing a repository completely can result in data corruption for
users, since a user's `rad/sigrefs` are the ground truth of their
state, and any fork of them results in errors in the protocol.
Instead of `rad rm`, we replace it with `rad clean` that removes all
remotes other than the local peer's namespace and the delegates'. The
delegates are also necessary to keep, since the repository's identity
is dependent on them.
Note that the remotes that were cleaned will be populated again upon
fetching, as long as they are tracked.
