Subject: [CI:DOCS] hack/bats - new helper for running system tests

Well, new to you. It's been something I've used for years.
Simple, but it takes care of a lot of housekeeping, and
makes it ever-so-much-more pleasant to invoke bats tests.
And when it's easier to run tests, tests get run.

+###############################################################################
+# BEGIN usage message
+
+usage="Usage: $0 [--root] [--rootless] [--filter=filename[:testname]]
+
+$0 is a wrapper for invoking podman system tests.
+
+   --root         Run only as root
+   --rootless     Run only as user (i.e. you)
+
+   --filter=name  Run only test files that match 'test/system/*name*',
+                  e.g. '500' or 'net' will match 500-networking.bats.
+                  If ':pattern' is appended, and you have a modern-enough
+                  version of bats installed, runs with '--filter pattern'
+                  which runs only subtests that match 'pattern'
+
+   --help         display usage message
+
+By default, tests ./bin/podman. To test a different podman, do:
+
+    \$ PODMAN=/abs/path/to/podman $0 ....
+
+To test podman-remote, start your own servers (root and rootless) via:
+
+    /path/to/podman system service --timeout=0
+
+...then invoke this script with PODMAN=\$(pwd)/bin/podman-remote
+
+   (You'd think Ed could be bothered to do all that in this script; but then
+   the flow would be 'sudo start-service; sudo run-bats; sudo stop-service'
+   and by the time we get to stop-service, the sudo timeout will have lapsed,
+   and the script will be hanging at the password prompt, and you, who left
+   your desk for coffee or a walk and expected to come back to completed
+   root and rootless tests, will be irked because only root tests ran and
+   now you have to wait for rootless).
+
+$0 also passes through \$OCI_RUNTIME, should you need to test that.
