Add support for service annotations

[aidanthewiz]

This update allows users to specify custom annotations using the Helm values file. This is useful for configuring cloud-specific features like internal load balancers on AWS.

Example command to adjust annotations with this change:

helm upgrade tika ./tika-2.9.0.tgz --install -n tika \
  --set image.tag=2.9.0.0 \
  --set service.type=LoadBalancer \
  --set "service.annotations.service\.beta\.kubernetes\.io/aws-load-balancer-internal=\"true\"" \
  --set "service.annotations.service\.beta\.kubernetes\.io/aws-load-balancer-type=\"nlb\""

You can also adjust the values.yaml file manually instead of using --set.

Hi @aidanthewiz thanks for the patch. I looked at it and it looks A OK. I’ll try to merge this week. 👍
