whenever the podman process is launched, it runs any file found in
these directories:
- /etc/containers/auth-scripts
- /usr/libexec/podman/auth-scripts
The current podman command line is passed as arguments to the
process.
If any of the processes fail, the error is immediately reported back
from podman that exits with the same error code.
[NO NEW TESTS NEEDED] requires a system-wide configuration.
