adjust cpu requests for failing ClusterSingletonManagerSpec, #30253 (#30873)

Browse source 
* ClusterSingletonManagerSpec is failing with Artery aeron-udp because of
  starvation slowness
* we use 5 nodes with 4 vCPU each
* ClusterSingletonManagerSpec uses 8 pods
* my thinking is that with the previous cpu request 1 it might
  schedule too many pods on the same node (if it doesn't distribute
  them evenly)
* with this new cpu request it should still be able to schedule 2 pods
  per node and that covers all tests except the StressSpec, which is
  anyway disabled
* also changed to n2 series and reduced idle-cpu-level
