      Workers will invoke this before configuring per-connector Kafka admin, producer, and consumer client instances to validate if all the overridden client configurations are allowed per the policy implementation.

      If there are any policy violations, the connector will not be started.

      Parameters:
      connectorClientConfigRequest - an instance of ConnectorClientConfigRequest that provides the configs to be overridden and its context; never null
      Returns:
      list of ConfigValue instances that describe each client configuration in the request and includes an error if the configuration is not allowed by the policy; never null
