HTTP/2 support for simple configurations. To enable HTTP/2 for more
complex configurations, to use lower-level HTTP/2 features, or to use
a newer version of Go's http2 package, import "golang.org/x/net/http2"
directly and use its ConfigureTransport and/or ConfigureServer
functions. Manually configuring HTTP/2 via the golang.org/x/net/http2
package takes precedence over the net/http package's built-in HTTP/2
support.
