Add API to write a deployment state to `/run/ostree/staged-deployment`,
along with a systemd service which runs at shutdown time.
This is a big change to the ostree model for hosts,
but it closes a longstanding set of bugs; many, many people have
hit the "losing changes in /etc" problem. It also avoids
the other problem of racing with programs that modify `/etc`
such as LVM backups:

We need this in particular to go to a full-on model for
automatically updated host systems where (like a dual-partition model)
everything is fully prepared and the reboot can be taken
asynchronously.

Let's be opinionated now, and our installed/ test story *is*
Ansible/STR. Merge `tests/fedora-str` into `tests/installed/`.
Rework the nondestructive tests into a separate playbook run, and parallelize
them for more efficiency.
The destructive tests are also changed to use Ansible more.
Add a higher level `run.sh` entrypoint and update the `README.md`
with some useful tips.
