Feature/rustfs config (#396)

* init rustfs config

* improve code for rustfs-config crate

* add

* improve code for comment

* fix: modify rustfs-config crate name

* add default fn

* improve error logger

* fix: modify docker config yaml

* improve code for config

* feat: restrict kafka feature to Linux only

- Add target-specific feature configuration in Cargo.toml for obs and event-notifier crates
- Implement conditional compilation for kafka feature only on Linux systems
- Add appropriate error handling for non-Linux platforms
- Ensure backward compatibility with existing code

* refactor(ci): optimize build workflow for better efficiency

- Integrate GUI build steps into main build-rustfs job
- Add conditional GUI build execution based on tag releases
- Simplify workflow by removing redundant build-rustfs-gui job
- Copy binary directly to embedded-rustfs directory without downloading artifacts
- Update merge job dependency to only rely on build-rustfs
- Improve cross-platform compatibility for Windows binary naming (.exe)
- Streamline artifact uploading and OSS publishing process
- Maintain consistent conditional logic for release operations
