Problem: Current Parallels/iMac fleet requires a human to create new images anytime dependencies change in the build scripts. Not only that, but we cannot free up a buildkite agent to pick up a different kind of job if it's just sitting around not doing anything and it's setup for a specific purpose (mac osx with xcode 10.2 OR nightly "clean" vms).
Solution: The Mac Anka fleet provides the flexibility of on-demand buildkite runs across mac minis with 12 cores and 32G of memory. Half of the fleet is limited to a single buildkite-agent, using the entire 12 cores; The other half runs two buildkite-agents with 6 cores each. This should greatly increase the performance and speed of running builds (which will use 12 cores) and tests (which only need 6). VM image layers are created just like docker and then pulled onto the host when we need them (or it uses the local copy if it's already been downloaded before).
