Proposed feature

Opensearch have the option to add custom anti affinity rules and we should expose it.

This would allow the option to ensure that two opensearch pods do not run on the same node in a zone.

The value that should be exposed: https://github.com/elastisys/compliantkubernetes-apps/blob/main/helmfile.d/upstream/opensearch-project/opensearch/values.yaml#L253-L256
