Add Extension:OAuth

The OAuth extension is used in Wikimedia production and many other places. It is needed if you have a wiki that is used as an identity provider for web apps used for editing that wiki. It is useful in general.

Hmm, how often do people use MediaWiki as an IdP outside of the WMF?

It is also useful if your wiki has bots, as an alternative to using passwords. For Wikibase it is required for the different web apps that come with it in a typical deployment. Outside of that, not sure.

The exact details are inaccessible to me now, but the OAuth extension is what I used to create a POC when I needed to provide authorization to an external agent (crawler) to gain access to an otherwise restricted MediaWiki (authentication required) without having to create a fake "user" in the Auth service. Instead, the OAuth extension allowed me to create a 'bot' OAuth consumer account with restricted set of permissions to use the MediaWiki API
