/**
*
* A service that can access and modify HTTP requests and responses
* as part of a filter chain.
* The overall external processing protocol works like this:
* 1. Envoy sends to the service information about the HTTP request.
* 2. The service sends back a ProcessingResponse message that directs Envoy
* to either stop processing, continue without it, or send it the
* next chunk of the message body.
* 3. If so requested, Envoy sends the server the message body in chunks,
* or the entire body at once. In either case, the server may send back
* a ProcessingResponse for each message it receives, or wait for certain amount
* of body chunks received before streams back the ProcessingResponse messages.
* 4. If so requested, Envoy sends the server the HTTP trailers,
* and the server sends back a ProcessingResponse.
* 5. At this point, request processing is done, and we pick up again
* at step 1 when Envoy receives a response from the upstream server.
* 6. At any point above, if the server closes the gRPC stream cleanly,
* then Envoy proceeds without consulting the server.
* 7. At any point above, if the server closes the gRPC stream with an error,
* then Envoy returns a 500 error to the client, unless the filter
* was configured to ignore errors.
* In other words, the process is a request/response conversation, but
* using a gRPC stream to make it easier for the server to
* maintain state.
