HAProxy 2.6 using HTTP/3 over QUIC

To run it:

1. Install VirtualBox
2. Install Vagrant
3. Call vagrant up from this directory:

$ vagrant up

This will compile OpenSSL and HAProxy and run them in the virtual machine.

4. Add to your /etc/hosts file:

192.168.56.20  foo.com

5. Import the minica.crt certificate into your browser (in Firefox: Settings > Certificates > View Certificates > Import) so that the provided SSL certificate is trusted.

6. Visit http://foo.com to see the site. The first time you access the site, it will return HTTP/2. Refresh the page and it will be HTTP/3.
