Start with a fresh RHQ instance, do not install jboss-as and jboss-cache plugin by default

Go to the admin UI, upload the jboss-cache plugin. UI will show a green bar, but the plugin is not showing up, no matter how often I press scan for updates, Server log shows [1]

Only then when I upload the as5 plugin, the cachev3 plugin shows up in the list.

We should show a message in the UI that the cache plugin is not deployed because of missing dependencies.
