Bug description
There is no way to provide "tolerations" to Kiali component

Istio 1.4.1

I've tried the following:

• Specifying values.kiali.tolerations - doesn't work, there is no such field in spec. Check this file:
  https://github.com/istio/operator/blob/9f96fae012485e3fbeeac88ca6b1ab4534f67dd7/pkg/apis/istio/v1alpha1/values_types.proto#L1791
  BTW, this also means that documentation is wrong, as the field is there:
  https://istio.io/docs/reference/config/installation-options/#kiali-options
• Specifying unvalidatedValues.kiali.tolerations via file - doesn't work, as all unvalidatedValues are ignored. Relevant PR for upgrade: upgrade cmd: using ICPS to compare changes between current install and target install. operator#671
• Specifying unvalidatedValues.kiali.tolerations - via cmd - doesn't work, as complex values are not supported. Relevant issue: istioctl manifest --set with a list does not work #19392
• Specifying through IstioControlPlane is impossible as there is no telemetry.kiali component

Looks like currently there are only three options:

• Deploying via Helm
• Deploying Kiali as a separate chart (not sure if it is possible)
• Adding additional tweak step to alter Kiali pod fields
