Create endpoint for receiving foodcritic results.

This is the naive implementation of creating an endpoint to receive the results
from Fieri (the cookbook evaluation service) and storing those results on the
specified Cookbook Version.

Fieri should issue a POST request to Supermarket with the cookbook_name,
cookbook_version, foodcritic_failure, and foodcritic_feedback. The last two
get stored on the record.

Todo:

- handle when the needed params are missing
- make sure the params are sanitized\*

\* unsure if I need to do this
