Example Realm REST Resource provider

You can deploy the provider by running: mvn package and dropping the jar under $KEYCLOAK_HOME/providers

When the server has started, open http://localhost:8080/auth/realms/master/hello and look for the message Hello master. You can also invoke the endpoint for other realms by replacing master with the realm name in the above url.
