Is your feature request related to a problem? Please describe.

In our current deployments using the Redis Cluster Template, we have a requirement to assign specific annotations to pods for better integration with our monitoring. The absence of support for podAnnotations in the Helm chart templates requires us to manually edit the chart each time there's an update.

Describe the solution you'd like

We would like to see the addition of a podAnnotations field in the values.yaml file, with corresponding support in the Redis Cluster Helm chart templates. This would allow users to define custom annotations for the pods directly in the values file, facilitating seamless integration and customization without the need to alter the chart directly.
Example implementation in the deployment.yaml template:

metadata:
  annotations:
    {{- if .Values.podAnnotations }}
    {{- toYaml .Values.podAnnotations | nindent 8 }}
    {{- end }}
