[Fideslog] Send an analytics event for each endpoint

[eastandwestwind]

For each deployment, we need to log:

• which API was accessed (and how - via the front end or directly via the API)
• if the call was successful or not
• if the call was not successful, we need to capture the error (the response code + error type)

Make sure we're not sending events in CI or local testing

The outstanding decisions to make here are:

• Where to store the API endpoint metadata — ie. which endpoint was accessed and from which source
• Where to build this into Fidesops — can this be a Router extension? We can use dependency injection at in FastAPI's APIRouter.
