Match against multiple responses instead of a single response.

[nizar-m]

As far as I understand, the match works like this

1. You send a request
2. Wait for a response
3. Parse the response and do a list of matches against the decoded response

But in some cases (like websockets), you will be sending one request, followed by expecting a list of responses.

How can we make tsung perform such matches against multiple responses after a single request?
