[mcgarrye]

This PR addresses #(4459)

• [x] Addresses the issue in full
• [ ] Addresses only certain aspects of the issue

Description

Creates the module, controller and service files for the new Feature Flag table. Allows for standard CRUD methods, as well as a list endpoint and an endpoint to add/remove jurisdiction associations with the flag (associateJurisdictions). Permissions are limited to admin only. Flags associated with jurisdictions will appear when jurisdiction data is returned.

How Can This Be Tested/Reviewed?

Start up the backend. Login as an admin, either through the API or partners portal. Test each endpoint:

• Create a feature flag
• Get the feature flag using the id returned ^^
• Update the feature flag using the id
• Get the feature flag to verify update
• Associate jurisdiction(s) with the flag
• Get the feature flag to verify association
• Get the jurisdiction to verify association
• Call the list endpoint
• Remove the jurisdiction(s) using associateJurisdictions
• Get the feature flag to verify removal
• Get the jurisdiction to verify removal
• Delete feature flag
• Call list endpoint to verify
