k8s-minion-manager should show money spent/saved

[shrinandj]

Is this a BUG REPORT or FEATURE REQUEST?:
FEATURE REQUEST

What happened:
k8s-minion-manager can intelligently switch between spot and on-demand instances. However, it doesn't provide information about how much money has been saved because of it. It will be good if the addon can provide that information.

What you expected to happen:
There should be an easy way of seeing the money spent and saved on a per IG basis.

Instead of trying to show the amount of money saved, we should log the price of spot instances and the number of spot vs. non-spot instances running at a given time.

Will not do. This project is end-of-life and is no longer maintained/supported.
