Nginx proxy_pass HTTPS/SSL/HTTP2 keepalive

[c0nw0nk]

I think from my understanding the proxy_http_version 1.1; is ignored over
https since everything works and that directive does what it states
proxy_HTTP_version for unsecured requests only it will be version 1.1 so i
don't think it has any negative impact on HTTP2/SSL.
