Acceptance Test Updates (#218)

* compute: don't pass choices

* blockstorage: don't pass choices

* DumpResource Function

This function prints a resource in JSON format but retains the actual
field name rather than using the name specified in the JSON tag.

* New DumpResource

This version just converts the resource into JSON. The original is
being left in git history for posterity.

* Renaming DumpResource to PrintResource

* Removing all print functions in favor of PrintResource

* Rebase reconcilliation
