Cause: the operator pod does not have memory requests
Consequence: in case of memory pressure on the node, the operator might be OOM-killed before other BestEffort containers
Fix: add memory request
Result: the operator won't be killed if there are other BestEffort containers on the node

The operator doesn't need limits. So expected results:
{
"requests": {
"cpu": "10m"
"memory": "<some value>"
}
}
$ oc get -o json pod cluster-image-registry-operator-5b6f5ff8b-rwwgp |jq ".spec.containers[].resources"
{
"requests": {
"cpu": "10m",
"memory": "50Mi"
}
}
