Feature: Global signout API
Description: Global signout - ability to log a user out of all devices/sessions from a backend service given a JWT.
Use-case: We currently are switching from AWS Cognito to Auth0. In our backend services, we use the global signout API (GlobalSignOut - Amazon Cognito User Pools) to log a user out of all devices when certain types of changes are made so that the devices are forced to retrieve updates to user information next time the user logs in. A similar feature would simplify our move to Auth0.
