Maybe it should be reduced to just one option and maybe it should contain the word "clone" to something that makes it more obvious that it's just copying or cloning the contents of the modules in the run-time image

After some more thought I've changed my mind and I've come to the conclusion that it makes sense to combine them. The latest patch uses `--unlock-run-image` as the "force" option which demotes the error to a warning.

Perhaps it makes sense to get some consensus on the naming parts at this point. The CSR seems a good vehicle for that and I've fleshed it out a bit now.
