Imported: Simpler Configuration - Nr. of VMs, iterations and repetitions

[DaGeRe]

This issue has been imported from an old repository. It was originally created by @Schattensilber at 2021-03-10T23:42:23Z with number #9

In case that cleanup of unit tests is not proper neither iterations and repetitions can be used (need be set to 0) and instead many VMs need be used.
Also (if the unit tests can be run several times in a vm) there doesn't seem to be any good metric for how many repetitions vs. iterations should be used.
It seems that both can be hidden to the advanced configuration. Instead there would be a switch 'All unit tests can be run multiple times in one VM' and a total number of times to run the test. (Or alternatively another config option, see #8 Simpler Configuration issue)
As far as i can see peass-ci should be able to determine a good configuration from these two inputs that are much user friendlier.
