Adjust ACL behavior for "none" mode and make query cache optional
This commit allows skipping authentication, permission checks, and certain filters (e.g., deletions, expirations) when the ACL mode is set to "none" (open relay mode). It also introduces a configuration option to disable query caching to reduce memory usage. These changes improve operational flexibility for open relay setups and resource-constrained environments.
