apisix-ingress-controller chart missing podLabels support

[luarx]

Chart version: apisix-ingress-controller v1.2.0

The deployment template renders pod labels exclusively via selectorLabels:

  template:
    metadata:
      labels:
        {{- include "apisix-ingress-controller-manager.selectorLabels" . | nindent 8 }}

There is no podLabels (or equivalent) value that gets merged into the pod template labels, making it impossible to add custom labels to pods for observability, scheduling, or policy purposes.

The apisix chart in the same repo supports this via service.labelsOverride. A straightforward fix for the ingress controller would be a deployment.podLabels value merged alongside
selectorLabels:

  labels:
    {{- include "apisix-ingress-controller-manager.selectorLabels" . | nindent 8 }}
    {{- with .Values.deployment.podLabels }}
    {{- toYaml . | nindent 8 }}
    {{- end }}

Note: deployment.podAnnotations is already supported. The missing piece is labels only.
