Related issue

Reported the issue on the fosite-example repo #32

Proposed changes

Currently revoke access or refresh token functionality is not working in the fosite-example repo because of the missing OAuth2TokenRevocationFactory as part of the OAuth provider initialisation so when loading the factories it didn't load and append the revoke handlers.
