Systest: Update kubernetes client-go dependency and configure rate limiter

[dsmello]

The code changes update the kubernetes client-go dependency and configure a rate limiter to prevent the client from being throttled. This improves the performance and prevents the client from being slowed down.

Motivation

To reduce the client throttling during the systest execution, the client limits was increased 4x

Test Plan

run the systest pipeline, and not find any client throttling warning.

• "due to client-side throttling, not priority and fairness, request"

TODO

• Explain motivation or link existing issue(s)
• Test changes and document test plan
• Update changelog as needed
