Add a service designed to query feature flags that are fetched from the API. This behavior is implemented in two classes: one for storing and querying the currently set flags and one for initially fetching them from the API.
It is designed like this so that we can test these functionalities on their own and so that the FeatureFlagService can be used in unit tests without any mocking. Any components that query FeatureFlags can just use the service directly and use the
set
method to manipulate feature flags directly in the test.Since this is adding a service that is not currently used by any components, there is no way to manually test this in production, however the whole service is covered by unit tests. This PR will not go through a QA review; please check and run the unit tests to verify correct behavior.
