Adds better support for CF deploy

- Removed the CF ruby gem that is deprecated and now using the go package
  installer
- Added tests to actually make sure all of the wonderful code is working
- Adds a setup step for the go package (don't really like the way this
  is being done)
- Updates README to reflect changes
- Switched out CF commands as they have become incorrect
- Changes target to api to be more symantically correct
