spec.containers[].resources.requests.cpu
- affects cgroup cpu.shares (relative share of CPU)
- if node is too busy, low requests means container could get starved

spec.containers[].resources.limits.cpu
- affects cgroup cpu.cfs_quota_us (microseconds available per period)
- works as ceilling, container will not receive more even if available for its cgroup
