detect/analyzer: add the type

Per rule type record properties of the type.

Example output:

    {
        "raw": "alert udp any any -> any any (msg:\"UDP with flow direction\"; flow:to_server; sid:1001;)",
        "id": 1001,
        "gid": 1,
        "rev": 0,
        "msg": "UDP with flow direction",
        "app_proto": "unknown",
        "requirements": [],
        "type": "pkt",
        "flags": [
            "src_any",
            "dst_any",
            "sp_any",
            "dp_any",
            "toserver"
        ],
        "pkt_engines": [],
        "frame_engines": [],
        "lists": {}
    }

Ticket: #6085.
