IMS OBv2.1 services have a registration endpoint to get client id
and secret.
This patch adds and implements the "register" method for the IMS
Open Badges Connect discovery system, to get the proper client id
and secret values.
In order to make easier to create and maintain new OAuth2 services,
a couple of classes have been added:
- discovery\* contains methods related to the discovery system. Until
now, only OpenID Connect was supported by Moodle so all the code was
centralised in api.php.
With this patch, as IMS OBv2.1 has a different discovery system, a new
abstract class (base_definition) has been added to be called and let
every discovery system (OpenID Connect, IMS Badge Connect...)
implement their own methods.
- service\* . Instead of keep adding methods to the api, the service
namespace has been created to store all the standard issuer services.
An interface (issuer_interface) has been created and all the services
should implement it.
This patch creates the "IMS OBv2.1" and "Custom" services and moves
the methods for "Google" service because it uses the OpenID connect
discovery system.
