Merge #11626: rpc: Make logging RPC public

cabff75 rpc: Make logging RPC public (Wladimir J. van der Laan)

Pull request description:

  This started out as a developer hack but now it's useful enough for general use. Unhide the call by moving it to `control` category. This makes it documented in `help`.
