SRT http hook call missing `ip` in request data

As part of the ingest flow we use http hooks to ensure valid incoming stream - for RTMP we currently use the ip part of request data - we need to do the same for SRT but the ip field appears missing in the request data

Please description your issue here(描述你遇到了什么问题)

Replay(重现)

Please describe how to replay the bug? (重现Bug的步骤)

1. RTMP tested with:ffmpeg -re -i live_005.mp4 -c copy -f flv 'rtmp://10.1.20.1:1935/broadcast/46746746746746746746'
2. SRT tested with: ffmpeg -re -i live_005.mp4 -c copy -f mpegts 'srt://10.1.20.1:10080?streamid=#!::r="/broadcast/46746746746746746746",m=publish'

Expect(期望行为)

Please describe your expectation(描述你期望发生的事情) I expect the ip field in the request data to be populated, regardless of RTMP/SRT protocol being used

I think part of the same issue is the lack of metrics for SRT based streams in the SRS api, here we have an SRT based stream:

{
  "code": 0,
  "server": "vid-45d790b",
  "streams": [
    {
      "id": "vid-1t26i17",
      "name": "6767676767676767676",
      "vhost": "vid-4p610s8",
      "app": "broadcast",
      "live_ms": 1657729474407,
      "clients": 0,
      "frames": 0,
      "send_bytes": 0,
      "recv_bytes": 0,
      "kbps": {
        "recv_30s": 0,
        "send_30s": 0
      },
      "publish": {
        "active": true,
        "cid": "4187ol33"
      },
      "video": {
        "codec": "H264",
        "profile": "Main",
        "level": "3.1",
        "width": 0,
        "height": 0
      },
      "audio": {
        "codec": "AAC",
        "sample_rate": 44100,
        "channel": 2,
        "profile": "LC"
      }
    }
  ]
}

You can see that it is active by looking at the publish section, yet there are no bandwidth details, or clients reported to be connected (even though we are able to view the stream), however some of this information is being captured in the Trace level logs, so it is available, eg:

So, I'm wondering if this is something that might get worked on soon, so that the API has some better visibility/stats over SRT based streams?
