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.

Our container-driven tests can't e.g. test SELinux sanely, and
have to support being run as root *and* non-root too.
Use redhat-ci to provision a VM and run tests directly there. These are
installed tests too.
