Reduce CPU and memory requests for Metrics Server Nanny

Metrics Server Nanny is a sidecar container that performs small computations every 5 minutes to scale Metrics Server resource requirements when cluster size changes. This change reduces the CPU and memory requests to free up unused resource.

**Release note**:
```release-note
Free up CPU and memory requested but unused by Metrics Server Pod Nanny.
