Make the loading of the Views in some order so that extension activation is faster

[mohitsuman]

Currently when OpenShift extension is started, the Activation time is too long and all the views are in refresh state at same time. This delays the Activation and users have to wait to even Login.

We need to device a strategy of loading the view in some particular order so that Activation is faster and Application Explorer View is loaded first. Once that view is ready, in background we can load the other views.
