CentOS machines hang on configuring network interfaces

[zer0def]

After taking a peek at lines 43-44: https://github.com/mitchellh/vagrant/blame/master/plugins/guests/redhat/cap/configure_networks.rb , I've found out the 'cause of my agonies.

You shouldn't be taking down any interfaces, until you're finished setting up config files for them, especially when you can't have any certainty that the interface you're putting to sleep isn't the one you're using for configuring an instance at the moment.

On top of that, touch and sed on lines 48-49 rely on the file not existing in the first place, which is simply a bad assumption, because it's being (unintentionally?) reused, eventually leading to assigning multiple values to keys.

Hi @zer0def

Can you please give us a Vagrantfile to reproduce this issue? Thanks!

Isn't it a dup of #2881?
