Subject: http: Add "if" option to the "match" object

This feature allows users to specify conditions to check if one
route is matched. It is used the same way as the "if" option in
the access log.

Example:

    {
        "match": {
            "if": "`${headers['User-Agent'].split('/')[0] == 'curl'}`"
        },
        "action": {
            "return": 204
        }
    }
