feat: remove dependency to crossplane/crossplane (#22)

fixes #20 

One caveat: we had to vendor the type for controller config. in a follow
up, we should already enable the new type for that, the same way, but
maybe better then with automatically copying… Or we just let the user
create a the controller config (or future thing) and patch the
unstructured.

Additionally we got rid of the controller-runtime dependency.
