docker artifacts tests is quite inefficient - takes a lot of time to try and fetch non-existants logs

(perhaps it's not a SCT issue?)
See https://jenkins.scylladb.com/job/releng-testing/job/artifacts/job/artifacts-docker-test/11/consoleFull for example:

We are wasting >2 minutes doing nothing, trying to collects logs we'll never have in this test.

The whole test takes 13 minutes, I'm sure we can cut it substantially.

I see that the log collection is part of SCT (

scylla-cluster-tests/sdcm/logcollector.py

Line 1625 in d199206

LOGGER.info("Start collect logs for cluster %s", log_collector.cluster_log_type)

)
