Reduce Metrics Server memory requirement
**What this PR does / why we need it**:
Reduces memory requirements of Metrics Server.
This was tested on GCE. On 16 - node cluster with 30 user pods per node, Metrics Server consumes ~60MB of memory. For larger clusters, the base value matters even less, and the memory utilization will be lower, therefore this change is safe.
**Release note**:
```release-note
Reduce Metrics Server memory requirement
```
