Base function for "Get Ready" UI screen from #163 WIP

This WIP pull request has the basic GET and most of the POST functionality for the #163 feature.

* You can access it from /dashboard/getready and test the basic deployment create & node assign function.
* You can create the deployment and network + range from the UI
* does not work put nodes into deployments until OS is working
* INCLUDES BDD TESTS for GET & Deploy Create.

This will NOT be connected to the menu until functionality is complete so it is safe to accept this WIP into trunk pending review.  We will talk about the design on the 6/25 design meeting.
