Cue compatibility for the Cortex config

[jtlisi]

Is your feature request related to a problem? Please describe.

I think we should consider experimenting with CUE as a language for storing and structuring the Cortex configuration file. Cortex has an expansive set of configuration options and I believe a configuration language that has validation as a first class language feature could be really helpful for new users of the project.

I'm not suggesting we transition from YAML to Cue. However, I think we should consider adding Cue struct tags to the Go Config struct and generate an associated Cue file to allow for experimentation.
