introduce podman machine

podman machine allows podman to create, manage, and interact with a vm
running some form of linux (default is fcos).  podman is then configured
to be able to interact with the vm automatically.

while this is usable on linux, the real push is to get this working on
both current apple architectures in macos.

Ashley Cui contributed to this PR and was a great help.
