Nodeclient

[jmservera]

This pull request primarily focuses on the implementation of a test client for the OCPP server and the addition of authentication features. The changes are spread across multiple files in the ocpp-server directory, including changes to the Makefile, OcppService.cs, and appgw.bicep. Additionally, a new client directory has been created with necessary files for the test client.

Here are the most important changes:

OCPP Server Changes:

• ocpp-server/Makefile: Added new commands test-client and test-client-badauth for testing a simple node client with good and bad authentication respectively. Also, the test-client command has been added to the .PHONY rule. [1] [2]
• ocpp-server/api/OcppServer/PubSub/OcppService.cs: Added a new authentication check when a new user connects. If the auth query parameter is present and not equal to a predefined value, an UnauthorizedAccessException is thrown. [1] [2]
• ocpp-server/infra/modules/appgw.bicep: Updated the application gateway configuration to use the Authorization header for authentication and changed the modified path and query string in the URL configuration. [1] [2]

Test Client Implementation:

• ocpp-server/client/index.js: Implemented a simple WebSocket client that connects to the server using the OCPP protocol. The client can send and receive messages from the server.
• ocpp-server/client/package.json and ocpp-server/client/package-lock.json: Added the ws package as a dependency for the test client. [1] [2]
• ocpp-server/client/.gitignore: Added a comprehensive .gitignore file for the client directory to ignore logs, cache files, dependency directories, and other unnecessary files.Add node client with basic auth
