This job tends to fail very often, but very frequently due to issues
with OBS itself - outside of our control. The output of the job can
still be useful to check manually, e.g. before releases.

Often, the VM fails to boot (even twice in the row, as already handled
by the test itself) which leads to false negative result.

These nightly/weekly tests fail far too often (at least on of the ~7
tests) and generate annoying notifications.

Adding yet another layer of retries should reduce the number of false
negatives without diminishing the value of the test (since the real
packaging issues are 100 % reproducible).

FreeBSD jobs are currently failing and blocking merges.

They can be restored once functional.
