feat: connect to different container by sessions

Based on the file summaries provided, the best label for this commit would be "feat". This is because the commit introduces several new features to the codebase, such as adding a new ESLint rule, adding a new property to a function, adding authentication middleware, adding a query parameter, and adding a new function to handle user authentication.: update authentication and session handling

- Add `"camelcase"` rule to ESLint configuration
- Add `containerId` property to the `newSession` object in the `createSession` function
- Add authentication middleware to the socket.io connection
- Add a query parameter `session_id` to the socket.io connection in `client.js`
- Add `defaultUser` function to handle user authentication
- Update the `authMiddleware` function to use the `defaultUser` function
- Add `defaultUser` function to handle user authentication in `auth.js`
- Update `getOrCreateContainer` function to use the `id` parameter instead of `name` parameter
