[Feature] Istio-based service mesh add-on components tolerate running on the spot node pools with the scalesetpriority=spot taint

[JamesDLD]

Is your feature request related to a problem? Please describe.
Istio system pod can't be scheduled on AKS spot node pools, indeed a specific toleration is required on pod that will run on spot node pools, see "Schedule a pod to run on the Spot node".

Describe the solution you'd like
A similar bug fix has been release during the "Release 2024-04-28":

• "The Istio-based service mesh add-on components can now tolerate running on the system node pools with the CriticalAddonsOnly taint."

Describe alternatives you've considered
Disable Istio mTLS on namespace where spot node pool will be deployed.

Additional context
Add an Azure Spot node pool to an Azure Kubernetes Service (AKS) cluster.
