uninit and auto-init

* Add uninit subcommand, which cleans up all etckeeper and VCS droppings
  in /etc. This is useful if you want to switch to a different VCS and
  don't have any history to preserve. (Preserving history and converting
  is of course possible, but significantly harder.)
* Run etckeeper init on initial install. Closes: #505772
  (The idea being that if someone doesn't want to use git, they can
  immediatly uninit to easily reverse this.)
* Document how to change the VCS used by etckeeper, without preserving
  any history. Preserving history left as an exersise for the reader.
  Closes: #515237
