No response

Description

In a k8s setup, there does not seem to be an obvious way to specify an admin password or user passwords (as ACL entries) seperated from the config file.

Proposed solution

Being able to use environment variables to fetch credentials from would allow one to store those credentials in a Kubernetes Secret and pass it to pika via env variables.

Alternatives considered

Another option could be to have the avbility to have multiple config fies which would allow to mount another config file from secrets that will held only credentials.
