Investigate "client-side throttling, not priority and fairness, request" when running the audit scanner

[fabriziosestito]

Is your feature request related to a problem?

The audit scanner was reported to cause client-side throttling when creating or updating policy report

Waited for 1.000137379s due to client-side throttling, not priority and fairness, request: GET:(omitted)/policyreports/4771d2aa-2573-4b47-961f-0d4fe9d8a9b1)

Solution you'd like

Maybe we need to tune QPS/Burst of the k8s client:

https://pkg.go.dev/k8s.io/client-go/rest#Config

	// QPS indicates the maximum QPS to the master from this client.
	// If it's zero, the created RESTClient will use DefaultQPS: 5
	QPS float32

	// Maximum burst for throttle.
	// If it's zero, the created RESTClient will use DefaultBurst: 10.
	Burst int
	
	// Rate limiter for limiting connections to the master from this client. If present overwrites QPS/Burst
	RateLimiter flowcontrol.RateLimiter
