Summary

Add support for Redis Cluster authentication with a separate username configuration.

Motivation

Some Redis Cluster deployments use ACL-based authentication and require both a username and a password. Passing the username as part of the password causes authentication to fail in these setups.

Changes

Introduce REDIS_CLUSTER_USERNAME to allow passing the username explicitly

Keep existing password-only behavior unchanged

Compatibility

This change is backward compatible. If REDIS_CLUSTER_USERNAME is not set, the current behavior remains the same.

resolves #31690
