Kubernetes performance guidance conflicts with Kubernetes deployment guide

[taroface]

Ryan Kuo (taroface) commented:

CockroachDB Performance on Kubernetes contains guidelines for CPU and memory resource requests that overlap and/or conflict with production guidance we have added to the single-cluster deployment doc.

Short-term:

• Update the relevant performance guidelines for accuracy
• Add a callout with a link back to this article in the deployment doc
• Edit this article overall

Longer-term (for another issue):

• This material may become part of a new K8s production guidance checklist.
• StatefulSet examples should be replaced with Operator examples, as this is now preferred over manual configs
• Decide how to present/expose the "performance version" of the StatefulSet config
