Ability to set PriorityClassName for ArgoCD Components in ArgoCD Custom Resource

[crtlatldel]

Is your feature request related to a problem? Please describe.
ArgoCD pods default to global default PriorityClass, risking eviction during resource contention.

Describe the solution you'd like
Add priorityClassName to ArgoCD Custom Resource for core components.

Describe alternatives you've considered
It is possible to create a global priority class, but then it would be applied to all pods, which brings us nothing.

Additional context
The same proposal is already exists in GitOps Operator.

We are facing the same issue. It would be great if we could preempt lower priority workloads to make sure Argo CD is running.

I agree, that's very relevant.
