tune openshift/release jobs resource requests for all the various pods

[jiridanek]

this is what we have in src-amd64, which is a clear overkill

  resources:
    limits:
      memory: 8Gi
    requests:
      cpu: '2'
      ephemeral-storage: 120Gi
      memory: 2Gi

when I tried to set this up, with the '*' thing, it did not work for me, the alternate override requests seemed to be ignored and all pods had the base requests
