Setting up LXD

LXD leverages the Linux Container (LXC) system to create light, effective system containers. However, before we begin to use LXC/LXD, we need to ensure we have it properly installed, initialized, and otherwise configured. In this lab, we will install LXD 3.0 Stable on Ubuntu 18.04 and ensure it's up and running.
