Code Review

This pull request introduces a new Netty-based RESTCONF endpoint and an example application demonstrating its use. The changes are well-structured. My review includes a few points for improvement:

• In Main.java, there's a redundant call to start the RESTCONF module which should be removed.
• In the RestClient test utility, the ExecutorService is static, which could cause issues in parallel test runs; it should be an instance field. Also, an explicit charset should be used when converting strings to bytes.
• In NettyRestConf.java, there are a couple of incorrect log messages in the shutdown procedure that need to be corrected or removed.
  Overall, these are good additions. Addressing these points will improve the robustness and clarity of the new code.

Code Review

This pull request introduces a new Netty-based RESTCONF endpoint as an alternative module, along with a community example application demonstrating its use. The changes are well-structured, adding new modules and examples clearly. My review focuses on improving code efficiency, maintainability, and adherence to Java best practices. I've suggested refactoring for better file handling, improving method naming conventions and reducing code duplication in the test client, making fields final where appropriate, and enhancing exception handling and code comments for clarity.
