[ Clean cherry-pick of #19302. This is a low-risk change with potentially very high ROI: the opportunity to catch interaction problems with updates in other system components. ] BATS 1.8.0 introduces tags: metadata that can be applied to a single test or one entire file, then used for filtering in a test run. Issue #19299 introduces the possibility of using OpenQA for podman reverse dependency testing: continuous CI on all packages that can affect podman, so we don't go two months with no bodhi builds then get caught by surprise when systemd or kernel or crun change in ways that break us. This PR introduces one bats tag, "distro-integration". The intention is for OpenQA (or other) tests to install the podman-tests package and run: bats --filter-tags distro-integration /usr/share/podman/test/system Goal is to keep the test list short and sweet: we do not need to test command-line option parsing. We *DO* need to test interactions with systemd, kernel, nethack, and other critical components. Signed-off-by: Ed Santiago <santiago@redhat.com>
