fd9cda8df9
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.
