[PATCH conductor]Conductor extended with hwp functionality

[Samridh]

This revised patchset adds Rspec tests for the templates (very basic).
@jayg: I've changed the local variable to an instance variable in the destroy action since I'm returning that data back to the client so it was needed.
The mapping from /api/hardware_profiles to /hardware_profiles is temporary. It is needed to test the cli functionality. It can be removed later
