mod_proxy_http doesn't support http2 yet. There is a separate
mod_proxy_http2, but I don't think it has been released.
It uses a new syntax to force an h2 connection.

I have Apache (2.4.18) setup and working fine with HTTP/2 on host-a. I can
establish HTTP/2 connections to host-a with any web browser. I also have
HTTP/2 and mod_proxy setup on host-b. I can proxy HTTP/1.1 requests from
host-b to host-a with any web browser. I can also establish HTTP/2
connections
