Follwing fixes in Ansible 7-9 for CVE-2023-5764 cating `AnsibleUnsafeBytes` &
`AnsibleUnsafeText` to `bytes()` or `str()` requires special handling. The
handling is Ansible specific, so it shouldn't go in the mitogen package but
rather the ansible_mitogen package.
`ansible_mitogen.utils.unsafe.cast()` is most like `mitogen.utils.cast()`.
During development it began as `ansible_mitogen.utils.unsafe.unwrap_var()`,
closer to an inverse of `ansible.utils.unsafe_procy.wrap_var()`. Future
enhancements may move in this direction.

A few changes are bundled in this
- Ansible 2.10.x and Mitogen 0.3.x are used to build nearly all images
(Ansile 2.3.x is retained for CentOS 5, because it uses Python 2.4).
- Tox is used to install/run Ansible, replacing build_docker_images.py
- A static inventory, identifying containers by name rather than ID.
- debian-test image is renamed to debian9-test
- debian9-test image is now based on debian:9
- centos6-test image is now based on moreati/centos6-vault
following the same scheme as centos5-test.
- Images are now uploaded to Amazon Elastic Container Registry (ECR).
See #809.
- Debian recommended packages aren't installed (e.g. build-essential)
- Python 2.x and Python 3.x are installed wherever available.
- Python Virtualenv is installed wherever available.
Unlike on Debian, some environment variables that tickle
getpass.getuser() are being inherited. So use getuid() instead.
Also install the doas binary on CentOS. CI was changed (I believe) to
shrink the configuration matrix, and now these tests run on CentOS too.
