45270: importccl: Fix flaky tests r=miretskiy a=miretskiy

Flakes in these tests were caused by stresstest command.
Under load, the node would experience liveness issues,
causing all running jobs to be cancelled.

Verified running effected tests under stresstest for 20+
minutes, and 5+k iterations without any failures.

Release notes: None
