Referencing a kubernetes secret for the value of OPENSEARCH_INITIAL_ADMIN_PASSWORD extraEnv

[vmm-afonso]

Is your feature request related to a problem? Please describe.
This is meant to avoid exposing the initial Admin password in the extraEnvs to someone with access to the cluster who's able to see the statefulset yaml

Describe the solution you'd like
Something like this:

  - name: OPENSEARCH_INITIAL_ADMIN_PASSWORD
    valueFrom:
      secretKeyRef:
        name: initial-admin-password
        key: password

referencing a key from a secret "initial-admin-password"

What about envFrom: [] :see https://github.com/opensearch-project/helm-charts/blob/main/charts/opensearch/values.yaml#L113C1-L118 ?

Thanks @dhardy92, @vmm-afonso can you please test with envFrom and see if that works for you?

envFrom works like a charm for me
