Description
On events like a request timeout, Envoy sends a locally generated response (the sendLocalReply function). But it doesn't use the response_headers_to_add config option. Which could be useful when response_headers_to_add has some diagnostic information (e.g. the %REQ(x-request-id)% which was added in #8683)
We can fix this by adding finalizeResponseHeaders calls before sendLocalReply calls, in functions like onUpstreamAbort.
