// defaultPodLimitsForDownwardAPI copies the input pod, and optional container,
// and applies default resource limits. it returns a copy of the input pod,
// and a copy of the input container (if specified) with default limits
// applied. if a container has no limit specified, it will default the limit to
// the node allocatable.
// TODO: if/when we have pod level resources, we need to update this function
// to use those limits instead of node allocatable.
