Improved support for helm releases with a different name

[taobojlen]

Proposed change

When deploying to a name other than posthog, e.g. my-posthog-deployment, we had to add the following config:

  kafka:
    externalZookeeper:
      servers:
        - "my-posthog-deployment-posthog-zookeeper:2181"

It would be nice if this was handled automatically.

Alternative options

Perhaps just some documentation would be helpful; it took a little while to debug this.

👋 Hi Tao,
thank you for opening this issue! What do you mean with deploying to a name other than posthog? The Helm release name?

[taobojlen]

Yes, sorry, that's correct! The Helm release name.

We should likely just improve that by in the chart/values rather than docs.

charts-clickhouse/charts/posthog/values.yaml

Line 434 in 27812d2

- posthog-posthog-zookeeper:2181

is where the posthog release name is implied from
