This would be a nice quality of life improvement.

Thinking out loud, take with a grain of salt:
At the same time, (afaik) our api accepts only ids almost everywhere. Hammer can do the resolution for you, if you're doing your own scripts then you can script around a bit to resolve names to ids yourself. I'm a little bit worried that introducing title or id lookup in a single endpoint would force us to implement it everywhere, otherwise the other endpoints would appear inconsistent and incomplete in comparison. Was this planned to be a first step or the whole thing?

The main idea behind this feature is to improve users' transition from Katello bootstrap to Global Registration. With the bootstrap script, you could easily use titles, but with the generated GR command, you cannot. Hammer might be the answer if you have access and permission to use it, which might only always be the case.
For example, a Satellite admin will create one command, which they then distribute among their colleagues for registration purposes.

I hope this PR won't create a precedent for it.

This is the whole thingy.

I know the RegistrationController is in the API module, but it's kinda a special kid on the block; for generating registration commands via API, we still use the _id parameters.
