Set proxy_http_version to ensure request buffering is disabled for GitLab Container Registry
According to http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_request_buffering:
When HTTP/1.1 chunked transfer encoding is used to send the original request body, the request body will be buffered regardless of the directive value unless HTTP/1.1 is enabled for proxying.
Closes gitlab-org/gitlab-ce#38678
