Add /_dendrite/admin/evacuateRoom/{roomID} (#2401)

* Add new endpoint to allow admins to evacuate the local server from the room

* Guard endpoint

* Use right prefix

* Auth API

* More useful return error rather than a panic

* More useful return value again

* Update the path

* Try using inputer instead

* oh provide the config

* Try that again

* Return affected user IDs

* Don't create so many forward extremities

* Add missing `Path` to name
