[keycloak-dev] dockerimage for jboss/keycloak-examples seems to be broken

[Stian Thorgersen]

Keycloak examples are deprecated and no longer maintained. We are now
focusing on the QuickStarts [1].

We should remove the example image as it really isn't a good showcase of
Keycloak due to the fact that it leverages Keycloak deployed to standard
WildFly server including JEE apps on the same container. This is not a
deployment we support and its also way to Java focused. Keycloak is a
solution for apps written any language, not just Java, but the fact that so
much of our examples/docs focus on Java has given the community a false
impression here.
