Pod disruption budget is not created when enabling HPA

[Fresa]

PodDisruptionBudget is only generated if .Values.podDisruptionBudget.enabled is true and .Values.replicaCount is greater than 1.

.Values.replicaCount is not set in the deployment manifest when using HPA, so the helm chart should take .Values.autoscaling.minReplicas in consideration as well when deciding if the PodDisruptionBudget should be rendered or not.

It's possible to workaround this by actually setting replicaCount to something that is greater than 1, but it's not very intuitive when using HPA.

Would you happen to have any suggestions on how to improve the chart?
Please feel free to suggest any changes via PR.

Thank you

I haven't tested this, but maybe something like:

{{- if and .Values.podDisruptionBudget.enabled (or (gt (.Values.replicaCount | int) 1)) (and .Values.autoscaler.enabled (gt (.Values.autoscaler.minReplicas | int) 1))) }}
