Automatically refactors wg prefixed globals to use MediaWikiServices config using Rector. Doesn't include files that set globals or files that fail CI. Rector Gist: https://gist.github.com/tchin25/7cc54f6d23aedef010b22e4dfbead228 * This patch uses a modified source code rector library for our specific use case and the rector will have different effects without it. A writeup for future reference is here: https://meta.wikimedia.org/wiki/User:TChin_(WMF)/Using_Rector_On_MediaWiki Change-Id: I1a691f01cd82e60bf41207d32501edb4b9835e37
