Add a new internal action=query&meta=oath Action API module that can be
used to check for OATH protection on a given user account. Using the
module requires a new 'oathauth-api-all' permission which is not granted
to any group by default. The permission is also added to the new
'oath' grant so that it can be used via OAuth and bot passwords.
Use of this API is security sensitive and should not be granted lightly.
Configuring a special 'oathauth' user group to grant the needed
'oathauth-api-all' permission is recommended.
This check is primarily useful as an internal network service in an
environment where MediaWiki and other applications are sharing the same
backing authentication store (e.g. LDAP) and the non-MediaWiki
applications would like to respect the OATH protections enabled on the
MediaWiki install.
