I can imagine something like this:
1. iterate over undefined groups in config;
2. select groups of interest (e.g. by prefix or some regular expression);
3. register options in them;
4. use those options.

Registered group can be passed to a plugin/library that would register its
options in it.

So the only thing that oslo.config lacks in its interface here is some way
to allow the first step. The rest can be overcomed with some sugar.
