RHEL 8's PAM has some weird bug where it rejects the *current* password
when changing an expired one. This isn't trivial to reproduce on the CLI
and thus has no bugzilla yet.
Cockpit 221 fixed storage test classes to all have different names, so
the "TestStorage" pattern now catches them all.
Also move the `image-download cirros` to simplify conditional blocks.
This provides retries on flakes, integrates tests-policy for known
issues, and outputs proper TAP format.
Once we work out the remaining kinks (unstable tests and proper test
class names), it will also be much shorter.
We currently have 3 versions of this script (one in fedora, one in rhel
cockpit and one in rhel cockpit-appstream).
With this patch we can keep this same file in all 3.
Also backporting hack in verify.sh.
Dynamically set $TEST_OS from /etc/os-release, and install chromium
directly on Fedora and from EPEL on RHEL. With these we can keep the
test in sync between RHEL and Fedora.
Also drop the obsolete resetting of system changes, that was fixed in
cockpit's tests.
