[hatched]

This removes the old scale-up UI from the inspector and fixes a bug where the new scale-up UI would be shown on subordinates.

Note: This branch requires #437 to land first

To QA

Use the mv flag
Deploy a charm, do you see the old scale-up UI? No? Good!
Deploy a regular charm and a subordinate, open the subordinates inspector after deploying. Do you see the new scale-up UI? No? Good!

Note: There is a bug with the subordinates being deployed https://bugs.launchpad.net/juju-gui/+bug/1342414

Code looks good, I'm assuming all those removed tests exist in the new scale up code? Can you verify that tests around having the right now of units show up are around somewhere?

In QA it was brought up that we can't remove this code yet because the non mv flagged code still relies on it for the scale-up functionality. I'm going to close this PR but leave the branch around for reference so that it can be re-applied in a couple weeks.
