APIs for Restaurant Group Table

[safchow]

Summary

• in Create Restaurant Groups Table #3, we will create a table for storing Restaurant Groups
• We also need to create APIs to create new restaurant groups, read them from the db, edit them to add restaurants as needed, and to delete them from the db

Goals

• POST API- create a restaurant group, restaurantIds can be empty
• GET API- get all restaurant groups
• PUT API- restaurant groups should be editable. Updating the list might be tricky, but we should provide a new list that overwrites the original list.
• DELETE API- restaurant groups can be deleted.

Implementation

• Since this is blocked until Create Restaurant Groups Table #3 is merged in, the db can be manually created with psql to test the APIs.
