[keycloak-dev] need to cache REST calls

IMO, the admin UI makes too many REST calls that will make the UI both slow and increase load on the backend. We should fix this after the 1st iteration of the admin UI. When the GlblCtrl initializes it should make one big REST require to down everything that makes sense in the first go and cache it in a global scope. (i.e. everything but users and role/scope mappings). UI components should render and link their models to variables in the global scope. I've already had to do this to make the realm-switching select box I added work in an integrated fashion. -- Bill Burke JBoss, a division of Red Hat http://bill.burkecentral.com
