Allow to collect any redshift attributes, prefixed rs to be exported along with a Maya Look Publish.

Testing notes

1. Enable Redshift
2. Create a mesh, publish model
3. Load model.
4. Then create the look
5. On the mesh in the lookdev scene, edit any of the Redshift attributes.
6. Publish look.
7. Load the model in new scene,

The attributes on the mesh should now match those set in the look at step 5)
