[FEATURE] Added cache identity to the StoreConfig GraphQl API Endpoint

[lewisvoncken]

Description (*)

For performance reasons you want to cache the StoreConfig output because the output is the same for every request but the returned value is based on the request type.

So for example:

In the cache all the data is saved but when you request only base_currency_code it will still cache the full response but only return base_currency_code.

Manual testing scenarios (*)

1. Enable FPC
2. Make an api get request for the storeConfig
3. First will be a cache MISS (see screenshot 1)
4. Try again
5. Now you will have a cache HIT (see screenshot 2)
