Could we also please add the clickhouse user's password to be referenced from a secret clickhouse.config.users.appUserPassword. Like suggested here: #125

clickhouse:
  config:
    users:
      # Existing inline password support (for backward compatibility)
      appUserPassword: "hyperdx"
      otelUserPassword: "otelcollectorpass"
      otelUserName: "otelcollector"
      
      # NEW: External secret support
      useExternalSecret: false
      externalSecret:
        name: ""
        appUserPasswordKey: "app-user-password"

I think this is a different use case

Thanks for the contribution. There's a merge conflict, probably around the version, that needs to be resolved. If you revert the Chart.yaml change, it should allow merging in main into your PR branch.

We also would like a changeset in the PR as well. You can create this by running yarn install from the root to install the changeset CLI. Then run yarn changeset and follow the prompts to generate the required files. We can't generate a release without that.
