// ServerRequest returns attributes for an HTTP request received by a server.
//
// The server must be the primary server name if it is known. For example this
// would be the ServerName directive
// (https://httpd.apache.org/docs/2.4/mod/core.html#servername) for an Apache
// server, and the server_name directive
// (http://nginx.org/en/docs/http/ngx_http_core_module.html#server_name) for an
// nginx server. More generically, the primary server name would be the host
// header value that matches the default virtual host of an HTTP server. It
// should include the host identifier and if a port is used to route to the
// server that port identifier should be included as an appropriate port
// suffix.
//
// If the primary server name is not known, server should be an empty string.
// The req Host will be used to determine the server instead.
//
// The following attributes are always returned: "http.method", "http.scheme",
// "http.flavor", "http.target", "net.host.name". The following attributes are
// returned if they related values are defined in req: "net.host.port",
// "net.sock.peer.addr", "net.sock.peer.port", "http.user_agent", "enduser.id",
// "http.client_ip".
