Create KubeVirt rate limiting static profiles

Is this a BUG REPORT or FEATURE REQUEST?:

/kind enhancement

What happened:
In #2197 we have introduced a user-friendly mechanism to adjust the rate limiting Query Per Second (QPS) and burst values. Now, we want to create static profiles such as highBurst hiding the raw configuration values.

What you expected to happen:
It would be more easy for users to high scale their clusters allowing them to create a high number of VMs in a bulk if we have a highBurst profile which hides the raw numbers:

apiVersion: hco.kubevirt.io/v1beta1
kind: hco
spec:
  tuningPolicy: highBurst

Values behind the highBurst profile are under discussion/testing in order to figure out possible downsides of increasing these values.

Issue tracked in: CNV-14170
How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

Environment:

  • HCO version (use oc get csv -n kubevirt-hyperconverged): 4.14.0
  • Kubernetes version (use kubectl version): any
  • Cloud provider or hardware configuration: any
  • Install tools:
  • Others:

@jcanocan is #2318 enough to consider this closed or are we targeting more profiles?

As far as I know, there's not plans for implementing more static profiles.

We are exploring if a dynamic profile that follows the kubelet rate limits configuration would be useful. You can find further details in: https://issues.redhat.com/browse/CNV-27873. Nevertheless, we can close this issue for now since this would be a more dynamic approach and I will open a new issue in the future.

Many thanks for the remainder.
