Christopher Faulet 6d0c3dfac6 MEDIUM: http: Add a ruleset evaluated on all responses just before forwarding
This patch introduces the 'http-after-response' rules. These rules are evaluated
at the end of the response analysis, just before the data forwarding, on ALL
HTTP responses, the server ones but also all responses generated by
HAProxy. Thanks to this ruleset, it is now possible for instance to add some
headers to the responses generated by the stats applet. Following actions are
supported :

   * allow
   * add-header
   * del-header
   * replace-header
   * replace-value
   * set-header
   * set-status
   * set-var
   * strict-mode
   * unset-var
