RequestReply: Create Data Plane

[Cali0707]

Problem The RequestReply resource needs a data plane which:

1. Receives events
2. If the events has the replyAttribute set, splits the attribute and checks if the RequestReply resource has a matching event it should reply to, if it does -> send the event as a reply to that http request.
3. If the event does not have the replyAttribute set, add the id and signed id as the correlationId event attribute, and forward the event to the RequestReply's resolved brokerRef url
4. After the timeout for a request, reply with HTTP 408 Request Timeout if the event was not already replied to.

Persona: Which persona is this feature for?

Exit Criteria Unit tests of the data plane forwarding events to a test http server, and replying correctly. Unit tests of the data plane replying with 408 when the timeout occurs.

Time Estimate (optional): How many developer-days do you think this may take to resolve? 2-3

Additional context (optional) Add any other context about the feature request here.
