+++ This bug was initially created as a clone of Bug #1906355 +++

Description of problem:
Due to a bug in the collection logic, there is a good chance that must-gather fails to collect the node logs randomly - and without a good reason.


Version-Release number of selected component (if applicable):
4.6


How reproducible:
Hard to predict, strongly related to timing. We expect this to happen pretty often


Steps to Reproduce:
1. just run the performance-addon must-gather image

Actual results:
node logs are missing with random chance (hard to predict). No error is reported if the logs are missing.

Expected results:
node logs should be collected 100% of times OR a clear error should be emitted if node logs can't be collected.
