Drop-in config #298
Description
Describe the feature
It would be lovely to support drop in config files, like how systemd accepts a target.conf.d/ file that allows other configs to be dropped in.
This allows nice layering of config by administrators, letting them swap in and out.
I am broadly interested in c12 trying to nicely expose layering as a first class concept, making it clear what config files are being used, understanding which layer / provider is the one providing config. Rust's Figment crates providers have metadata that kind of decorate the config.
