SRS2.0 HTTP-FLV, can it also forward the client IP?
RTMP requests have the client's requested IP,
but FLV does not.

RTMP
{"action":"on_play","client_id":116,"ip":"172.17.0.1","vhost":"defaultVhost","app":"live","stream":"livestream","param":"?token=123&salt=456","pageUrl":""}

FLV
{"action":"on_play","client_id":113,"ip":"","vhost":"defaultVhost","app":"live","stream":"livestream","param":"?token=123&salt=456","pageUrl":""}

When playing HTTP, there is no on_connect, only on_play, and on_play does not have an IP.

(gdb) p *req
$2 = {_vptr.SrsRequest = 0x95b3d0 <vtable for SrsRequest+16>, ip = "", tcUrl = "rtmp://__defaultVhost__/live", pageUrl = "", swfUrl = "", 
  objectEncoding = 0, schema = "http", vhost = "__defaultVhost__", host = "__defaultVhost__", port = "1935", app = "live", param = "", 
  stream = "livestream", duration = -1, args = 0x0}

When converting an HTTP Request to SrsRequest, the IP information is lost and cannot be recovered.

[2019-12-26 02:30:41][trace] srs on_play: client id=113, ip=172.17.0.1, vhost=__defaultVhost__, app=live, stream=livestream, pageUrl=
127.0.0.1 - - [26/Dec/2019:02:30:41] "POST /api/v1/sessions HTTP/1.1" 200 1 "" "SRS(Simple RTMP Server)2.0.268"

Directly accessing HTTP-FLV already provides IP information, but we also need to consider the scenario of accessing through an HTTP proxy.

SRS2, HTTP direct access, and proxy are all supported.

SRS3 is also supported.
