MINOR: http-rules: Add capture action to http-after-response ruleset

It is now possible to perform captures on the response when
http-after-response rules are evaluated. It may be handy to capture headers
from responses generated by HAProxy.

This patch is trivial, it may be backported if necessary.

   This stops the evaluation of the rules and lets the response pass the check.
