Research how to expose model and feature metadata from a service

[nevillelyh]

What and how do we want to expose metadata about a model and feature spec/settings:

• how do squads want to consume it?
• what is this information gonna be used for?

Requires talking with the squads/cream and figure out what can we do here. Might be that we will leave this open for some time, until we have better set of requirements.
