Remove mitigations of CI problems

Problem to solve

While we were experiencing problems with CI pipelines in the past months some mitigations were put in place. Like:

• Retrying the systemtests once if it fails #628 (closed). Now that the problems have been fixed the only thing that this retry achieves is hiding future problems. The tests should not fail, and if they fail we should have a ticket were they are tracked, the reason is understood and it is ok to just retry.
• Adding extra sleep to reduce the failure rate of eviction #662 (closed) #658 (closed), there is no longer a need for this. I introduced this as it was reducing significantly the eviction failures.

Now that these issues have been solved we can remove these mitigations.
