Create a reusable angular based wizard

Summary:
Create a reusable angular based wizard

Motivation:
The initial driving motivation is to redesign the launch instance wizard based on a modern, responsive design that is based on client side rendering using angular.

This was discussed in numerous sessions at the Kilo summit that the right direction going forward is to move this to client-side. AngularJS appears to be the first choice primarily because of its structure and MVW framework.

Although the desired target is launch instance, we want to separate out the basic wizard with a reusable framework in angular that will first be used to prove out very simple workflows, perhaps network creation. This will enable easier reviews and cleaner separation. We will co-develop it with the more complicated launch instance work, but will ensure good separation is maintained.

Description:

The wizard will be as lightweight as possible, but still allow for customizable text, localization, customizable per-worfklow number of steps.
