Move stat descriptions out of the config.
This lists stat descriptions in an Erlang term file to avoid abusing the config system. Uses a file in CouchDB's priv directory that is a list of three-tuple terms. git-svn-id: https://svn.apache.org/repos/asf/couchdb/trunk@829304 13f79535-47bb-0310-9956-ffa450edef68
