Title: bugfix: centos dns resolution issues because of natdns proxy.

Gusteau is currently forcing natdnsproxy on.

This is causing [5 second dns resolution on Centos](https://github.com/mitchellh/vagrant/issues/1172). There is more info on auto_nat_dns_proxy virtualbox setting [here](https://github.com/mitchellh/vagrant/issues/1313).

e.g. The following has no effect:
```
# Vagrantfile
config.vm.provider :virtualbox do |vb|
vb.auto_nat_dns_proxy = false
vb.customize ["modifyvm", :id, "--natdnsproxy1", "off"]
vb.customize ["modifyvm", :id, "--natdnshostresolver1", "off"]
end
```
