[KYUUBI #5717] Infer the proxy user automatically for delete batch op…

…eration

# 🔍 Description
Infer the batch user from session or metadata, user do not need to specify the proxy user anymore.

This pr also align the behavior of BatchesResource with that of SessionsResource and OperationsResource(no proxy user parameter).

For Kyuubi Batch, Session and Operation, these resources have the user attiribute.

So we only need to check whether the authentication user has the permission to access the resource.
