Nginx / Apache configurations should be handled by deployment scripts

[gregharvey]

Historically we've depended on Puppet to put the necessary Nginx and Apache configurations in place. We should change this so the deploy scripts place the configs if they're not there. We should make the vhost config location a variable while we're at it, and put these configs in the same directory.

Additional note here, it's been pointed out you could allow project-level vhosts in config as well, e.g. you could potentially put the path to a vhost in the app repo in config and then link that to your web server sites-enabled directory.
