This patch works several files that were not in common use back into the documents they should live with. The intended end result of this activity is to make common as lean as possible so it can be more easily translated. Also: Don't include configdrive table in user-guide since it's not relevant for audience Change-Id: Iacd5c68c639e60e8c711cb18351543e477444299
