Add Support for hhvm about nginxconfig.io

[0xb4lint]

Thanks for the example @ARKKYN!
I've deployed the support of the backup PHP server.

Addition of PHP-FPM support would be awesome!

Hello @ARKKYN!

I've added support for multiple HHVM sockets.

@ob-jon fallbacking to PHP is another challenge 😉

[ARKKYN]

Thanks but it still needs fallback for hhvm when it crashes to fallback to php-fpm
like or similar to below

upstream php {
        server unix:/run/hhvm/hhvm.sock;
        server unix:/run/php/php7.1-fpm.sock backup;
}
try_files $uri =404;
