Add protocol header for upstream service

[chnliyong]

The upstream service such as web rendering may sometimes need to know the incoming request's scheme(http or https) from client.
Conventionally use the http header X-Forwarded-ProtoX-Forwarded-Proto

I think you can use the proxy-rewrite plugin.

I think you can use the proxy-rewrite plugin.

I thought this is a very commonly requirement if apisix is used as a reverse proxy to offer ssl offloading, and configure the proxy-rewrite for all routes is tedious.
We may add a option such as enable_protocol_forwarded and protocol_forwarded_header in config.yaml if we don't want this as default. Actually, I would like this be default.

      proxy_set_header ....
      proxy_set_header X-Forwarded-Proto $scheme;
      proxy_set_header ....

I got your point.
I think we can add this to /bin/apisix directly.

you can send email to mailing list to discuss with more developer.
