Incorrect limits displayed for multi-container pods

Summary

Pod resource limits are incorrectly calculated in kubectl describe node when all the following conditions are met:

1. The pod has multiple containers (including init containers).
2. At least one container specifies a resource limit.
3. At least one container does not specify a resource limit for a resource type for which another container has specified a resource limit.
