Provide instructions on how to secure each project and package

[ctron]

Each project chart and package chart should provide some information on how to secure the installation. Including, but not limited to:

• Installing custom certificates
• Setting custom credentials

Ideally the package charts only need to reference to project charts.

Hi @ctron this would be really good, I am looking to add tls certs for my hono install currently and the values.yaml is not giving me many clues. Any tips in this issue would be much appreciated initially.
