initialize redis_pwd, read /app/config/redis-auth/auth only when the file
exists, and preserve the legacy AUTH fallback using an unset-safe check.

Where is AUTH variable initialized ? Is it expected to be set as environment variable ?

It WAS the old way of passing it before we changed it to the mounted file. The missing file can either indicate a misconfiguration, or that this is one of the pods not yet rolled out during upgrade so the AUTH var is still part of the pod spec. See the JIRA issue for the exact chain of events I believe lead to this regression.
