feat(aiohttp): Add failed_request_status_codes (#3551)

`failed_request_status_codes` allows users to specify the status codes, whose corresponding `HTTPException` types, should be reported to Sentry. By default, these include 5xx statuses, which is a change from the previous default behavior, where no `HTTPException`s would be reported to Sentry.

Closes #3535
