Deflate the hardware configuration

Hi,

What about deflating this kind of stuffs?

  - name: beam_shutter
    id: beam_shutter
    protocol: bliss
    address: beam_shutter

  - name: tomo2cam_y
    id: tomo2cam_y
    protocol: bliss
    address: tomo2cam_y

  - name: tomo2cam_magnification
    id: tomo2cam_magnification
    protocol: bliss
    address: tomo2cam_magnification

It's only about picking one as the main attribute, id or address.

  - address: beam_shutter
    protocol: bliss

  - address: tomo2cam_y
    protocol: bliss

  - address: tomo2cam_magnification
    protocol: bliss

Even more i would like to merge protocol and address together

  - address: bliss://tomo2cam_y
  - address: bliss://tomo2cam_magnification

And finally this address could be used inside the layout file, without need of defining twice the stuff in hardware and layouts, and at other places.

What do you think?
