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. [NO TESTS NEEDED] Signed-off-by: baude <bbaude@redhat.com>
