Add docs about connecting kerberose-enabled yarn cluster for TaskManager

We need to provide the documents about how to connect kerberose-enabled yarn cluster for TaskManager.

Look for existing TaskManager documentation in the OpenMLDB docs, likely under deployment or configuration. Find references to YARN cluster setup and Kerberos authentication. The goal is to add a new section or guide explaining the connection steps, including any necessary configuration files or environment variables. Check if there are existing examples for other authentication methods to follow a similar structure.
