Config schema for superfile configs, for LSPs

[lazysegtree]

Here is a sample scheme from @NSPC911

https://gist.github.com/NSPC911/a9b944621e849196e8ace632d3cb35fb

We would want to have a scheme committed in the repo and have it updated each time the config is changed.

I would rather have an auto-generated or manually generated schema committed in spf repo, updated for any config change.
