Introduce AppleContainerBuilder and AppleContainerConfig to run tasks with Apple's `container` runtime (https://github.com/apple/container), which launches one lightweight VM per container on Apple silicon via Virtualization.framework. Wires the builder into ContainerBuilder.create() and Session.getContainerConfig() so it can be selected via the `appleContainer` config scope.

Wouldn't it always have to use the local executor? |

Yep, but strictly speaking executors are decoupled from executors. Then, who knows, k8s clusters running mac metal instances .. 😄 |

Low impact, merging this since it's a nice to have in next release. @bentsherman feel free to follow up in separate pr if you feel there's something it could be improved |
