Add basic interaction with containers and images

[afbjorklund]

It would be nice to at least be able to display the running containers and stored images...

• nerdctl.lima container list - https://github.com/afbjorklund/lima-gui/wiki/Containers

• nerdctl.lima image list - https://github.com/afbjorklund/lima-gui/wiki/Images

Start with nerdctl (containerd), but should be simple to add docker and podman support:

• docker.lima

• podman.lima

[afbjorklund]

Also:

• version

• info

With the basic functionality of being able to select engine (nerdctl/docker/podman) to use.

This is just implemented using limactl shell, no need to mess with any local client programs.
