Podman machine enhancements

Podman machine remove is now called `rm`.

Podman machine create now supports resizing the image to the value of
--disk-size as provided.  The default is to 10G.

Added systemd unit file on guest via ignition that sends a Ready message
to the host over a virtio-socket so that we know when the VM is booted
and ready for use.

Podman machine commands no longer require a VM name as an argument.  A
default VM name is defined and if no VM name is provided as a arg, the
default will be used.

[NO TESTS NEEDED]
