tls_server_name required

[xialvjun]

Add options like reverse_proxy especially for upstream.transport[http].[tls_server_name] so we can:

:8080 {
  route {
    forward_proxy {
      upstream https://username:password@ip.ip.ip.ip:443 {
        transport http {
          # specify domain and ip to avoid dns query on local machine in case you have a tun device default route to it
          tls_server_name domain.com
        }
      }
    }
  }
}
