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.
- Introduced a new package `run` with a `Relay` struct to manage the lifecycle of a relay instance.
- Implemented `Start` and `Stop` methods for initializing and gracefully shutting down the relay, including options for log capturing and data directory cleanup.
- Added methods to retrieve captured stdout and stderr logs.
- Enhanced configuration handling for data directory and logging based on user-defined options.
