Publishing a LXD Image

While a number of public LXD images exist, we do not want to be stuck updating the same base image in perpetuity. Instead, we can take an already-configured container and publish it to a remote so it can be pulled down and used as any other image. In this lab, we do just that -- create a new image, then try it out on a few different LXD hosts!
