Description
Is your feature request related to a problem? Please describe.
This feature fulfils two demands. One is to deploy a fully configurable Authorization Server to test some Oauth 2.0 flows in Selenium, in particular, opaque access tokens. The second is to add Spring Authorization Server to the list of explicitly supported OAuth 2.0 identity providers by RabbitMQ.
This authorization server should work with both tokens, JWT and opaque ones.
Describe the solution you'd like
Create a java project under selenium with all the necessary code to support Authorization Code with PKCE flow and all the necessary endpoints (authorize, token, discovery) in addition to the introspection endpoint.
This feature is necessary in order to complete another feature.
