Added recipe meta model

Necessary to handle API response metadata so we can have distinct models for data and metadata.

RuboCop has been updated to ignore the parameters because RuboCop still doesn't have the ability to distinguish between whole value objects and standard objects (and we need safe defaults in this case).

Milestone: minor
