Feature flag consumption

[ludtkemorgan]

In order to use this new feature flag system we will need to make the following changes so that we can access the flags as well as updating/creating them.

• Create new featureFlag controller/service (could potentially combine with jurisdiction controller)
  • Endpoint to create new feature flags
  • Endpoint to get all feature flags
  • Endpoint to add/remove feature flags to a jurisdiction
  • Endpoint to add/remove feature flags to all jurisdictions
• Update existing endpoints:
  • Jurisdiction get endpoints should return the attached feature flags
