Create an LXC create template for machinectl
This change creates a simple LXC create template for machinectl. This
will allow out container create process to use less storage and more
efficently build containers which will speed up operations and
deployments. This also begins to leverage common tools already on the
systems we support there by simplifing how cache is stored, containers
are built and the general management of images within a host.

The new lxc container create template, and the features it provides,
will only impact new containers created allowing deployers to safely
adopt this change in any existing environment.

features:
- A new LXC container template has been added which will allow us to better
manage containers on the host machines we support. The new template uses
the `machinectl` command to create container rootfs using the existing
cache. This in-turn will provide easier management of container images,
faster build times, and the ability to instantly clone a container (or a
given variant) without impacting a containers state. This new lxc container
create template, and the features it provides, will only impact new
containers created allowing deployers to safely adopt this change in any
existing environment.
