cluster_addr documentation insufficient

[ilsaloving]

Is your feature request related to a problem? Please describe. The documentation (website/content/docs/configuration/index.mdx) claims you can configure the cluster_addr dynamically but it's really not clear how to do that.

This can be dynamically defined with a go-sockaddr template that is resolved at runtime.

Describe the solution you'd like A clear explanation of what is required.

Describe alternatives you've considered I tried setting the value to "https://{{ GetPrivateIP }}:8201", and that worked, but that was purely a guess.

Explain any additional use-cases
