[Feature request] site block workers

[henderkes]

It would be nice to define these inside a php_server block.

one.example.com {
    root /path/to/app/public
    php_server {
        root /path/to/app/public
        env APP_ENV one
        worker worker.php # inherits APP_ENV one
        queue_worker queue_worker.php  # inherits APP_ENV one
    }
}

Which also means that the global directive's name shouldn't be prefixed with m#.
