API: Add user IPs and access times tracking

[mr1cloud]

Added IpTimeMap method, GetStatsOnlineIpList RPC and CLI command for tracking client IPs and access times.

Execute:

.\xray.exe api statsonlineiplist -server="127.0.0.1:8080" -email user1

Result:

{
    "ips": {
        "192.168.1.2": {
            "seconds": "1738845962",
            "nanos": 572060848
        }
    },
    "name": "user>>>user1>>>online"
}

New PR after corrections from #4347

应当把它放在 command 文件夹下面并把 metadata 改为 Xray 的，还有这个文件复制进来没有 license 问题吧

[RPRX]

你改好后，这个 PR 我来合并（时机成熟时，现在 main 在搞 MMDF）

[yuhan6665]

Guys please don't copy protobuf code in project.
protocolbuffers/protobuf#5131

[mr1cloud]

@yuhan6665 I did that last time, but my PR was canceled: #4347
Then how to work with ptorobuf in this project, I would appreciate an explanation.

[RPRX]

可以换成自定义的结构吗？不引用外部 proto

[mr1cloud]

Yes, i can do it. I'll just say it again, @yuhan6665 told me to use google protobuf, so that's what I did...

[yuhan6665]

Please don't define your own timestamp, use protobuf version, properly.

[mr1cloud]

@yuhan6665 like I did last time, right? #4347

[RPRX]

我不太了解 proto 这里是怎么回事

那如果引用外部 proto，执行 go run ./infra/vprotogen 前都要先把那个外部 proto 拉到本地？

[mr1cloud]

@RPRX It turns out that it is...

[RPRX]

所以 google standard timestamp 有什么特别的好处吗？我们不是只需要 timestamp 的值而已？

[mr1cloud]

Initially, I just did the display in seconds, but I was told to use google timestamp. I did so, everything was accepted, but there was a rollback due to the lack of file data during execution: go run ./infra/vprotogen

[RPRX]

我想了解下 @yuhan6665 的看法，或许这里我们只是需要一个值？

[RPRX]

如果需要先拉下来外部 proto 就比较难受了，我经常 go run ./infra/vprotogen

[yuhan6665]

Using google protobuf is not rocket science, I'm sure we (whoever run into issue) can fix it.
I'm just saying this PR copying of timestamp is not proper usage

[RPRX]

主要是看到了 then convert the time.Time to standard google.protobuf.Timestamp

既然没有特别的需求，直接拿个 uint64 存 timestamp 吧

[mr1cloud]

So I'm just returning the timestamp in uint64?

[Fangliding]

timestamp轻松加愉快为什么要搞个这个东西进来

[mr1cloud]

No no, I'll just return the timestamp (uint64), okey?

[RPRX]

timestamp轻松加愉快为什么要搞个这个东西进来

没看懂

[RPRX]

@mr1cloud just uint64

[mr1cloud]

Okay, I think that's it.

Execute:

.\xray.exe api statsonlineiplist -server="127.0.0.1:8080" -email user1

Result:

{
    "ips": {
        "192.168.1.2": 1738924438
    },
    "name": "user>>>user1>>>online"
}

[RPRX]

改成 int64 吧，不用转换类型了
