Report Response Context #873
Description
We should add the Response context to the types, then add it to events generated by the actix and tower integrations.
This will allow users to filter based on status code in before_send.
This came up with client errors previously being reported to Sentry. Now that we don't do that, this issue is less pressing, but it still would allow users to filter on before_send. This is needed in Rust SDK, since we don't have hints.
