Subject: [PATCH] Jenkinsfile: compress qcow2 before archiving on failure

Use cosa to compress the qcow2, so we get multi-threading, before
archiving. Otherwise, we risk overloading the Jenkins master PVC before
too long.

Another strategy eventually would be to still upload to S3 (see [1]
which is related to this). But even then, we'd still want to compress
first.
