Should this package include a single logout handler?

[vparpoil]

In order to handle single logout (logout of all apps using the oauth2-server as identity provider), this package could include a single logout route, handled by Express.

This route is project agnostic and then could be included. Single log out needs to remove the tokens so it makes sense to include it in the package.

I can work on a pull request for this feature if you feel it's usefull

@vparpoil sorry I missed a few things in the recent months. I like the idea and I'd love to see an implementation. Please consider a few factors:

• the route must be secured, so only authenticated users can call it (oauth2server.authenticatedRoute)
• it must remain entirely optional to be created, means it must be possible to operate without it
• please run tests and lint accordingly and add new tests to your implementation
