Expose HTTP endpoint to export live config in yaml format

[pracucci]

Given the intention to deprecate CLI flags, I'm wondering if it's useful / required to give users a way to convert CLI flags to yaml. An option - for users already running Cortex clusters - may be introduce an HTTP endpoint to export the live config (which is the result of yaml + CLI flags + defaults) as yaml.

I'm not super sure this is useful, so I would like to gather some feedback and real use cases first.
