Create a Multi-Master Salt Environment

When running critical applications and infrastructure, we want to be sure to avoid any single point of failure — such as our Salt master. To allow for redundancy, we can configure multiple Salt masters that work with our minions, all of which run "hot" and can communicate with all minions. In this lab, we'll take an existing Salt master and replicate it.
