Add nspawn container driver
This change adds an nspawn container driver which will enable deployers
to run clouds with systemd-nspawn instead of LXC. This adds "nspawn" to
as an option to the `container_tech` variable. To support this change,
The inventory generation tools have been updated to allow for a
new group named `nspawn_hosts`. All of the container connectivity and
setup are stored within the integrated repo under the new templates
directory.

The addition of "nspawn" container driver enables the ability for
deployers to change, or mix container technologies within a single
deployment without needing to change our well defined network
topology or storage layout.
