I'm working on adding theme support to the admin console, and the plan was to use the
what we have for login and account forms.
To get this to work I can either use a Servlet or a JAX-RS endpoint to deliver resources.
My preference is to use JAX-RS and have everything done through RestEasy, effectively
dropping Servlets (and web fragments). This would also let us drop '/rest' from
the other endpoints (so it would be '/realms/keycloak-admin/tokens/login' instead
