How to pack charms on CentOS 7 using charmcraft

So, you have the situation where you need to pack a newer charm that uses the latest and greatest bells and whistles Python provides, but the default Python on CentOS 7 (Python 3.6 to be exact) is too old? This quick guide will tell you how to get a CentOS 7 packer instance up and running using libvirt/kvm packing charms before you know it.

Originally I was going to use a CentOS 7 virtual machine with LXD, but it was having consistent connectivity issues. Even though the virtual machine had an IP address, lxc was incapable of reaching. Also, the virtual machine struggled to connect to the internet after it was first started, requiring an IP address to be manually assigned with dhclient -v
