Description
*Title*: access log: add a new response flag to indicate request handled locally by Envoy
*Description*:
This is started from the discussion in https://github.com/envoyproxy/envoy/pull/12912#discussion_r490613876 that we could have a more general way to indicate that the request is handled locally by Envoy (sendLocalReply) instead of by upstream.
The response flag could be `RESPONDED_BY_FILTER` and deprecates the other `response_from_cache_filter`. The `RESPONSE_CODE_DETAIL` can be used to learn more details.
