We want adapters, PicketLink already has quite a few, can we utilise that?
Can we provide a single Keycloak PicketLink adapter for everything Java, and then get the
correct level of integration and features for:
* Fuse
* BRMS
* WildFly/EAP (Elytron)
* JavaEE (WildFly/EAP, Tomcat, Jetty)
* Spring
* Anything else?
Obviously the main benefit is that we don't have to write our own, but would
potentially also allow users to switch to another IdP without recoding.
