Comment 1 for bug 1566920

I fixed the real issue of this bug which is that you should not be able to modify the power parameters of the machine unless one rack controller is connected to that region controller.

The other issues that you pointed out can be solved at a later date as the UI error reporting is an issue all across the UI and we really need to improve on that. Split out the form I don't think adds much in this case as you still need a connected rack controller to validate the power parameters.
