        This method takes in current status and request and try to determine whether to change partial update config. The check logic is: Step (1): If there is explict request, we will respect the request and maybe update config if new request value is different from existing config value. In this step, if we are enabling partial update, we will also perform a dry run to validate schema. If validation fails, it will throw exception and fail the whole request. Step (2): If there is NO explict request and store is being converted into hybrid store, we will check the cluster config and store's latest A/A config to see whether we should by default enable partial update. If so, we will also perform a dry on to validate schema. If validation fails, it will swallow the exception and log warning message. It will not turn on partial update and will not fail the whole request.
