I was playing some significant amount of time today to find a combination that passes. At some point the following seemed to be a good combo, with the cloud access intro one either added or not, but then I couldn't reproduce the passing status. Looking at the resource log it seems that there wasn't really proper garbage collection during the session as the restarts were not real restarts.
So, apparently one needs to do this with brand new sessions and that just makes the task even more tedious.

So, I could imagine a better solution would be to enable back everything, and we keep an eye out to the resource problem in individual PRs -- then it's more clear which ones are affected (as we only test the ones that have been changed).

I manually iterated over this one, and it looks like we can only remove one notebook from the ignore list for circleCI, all the rest is running into memory limit issues, so at the end of the day the --execute-parallel 1 doesn't really have any effect on this problem.
