Notify the delegate when device attestation completed with device info for additional verification. If this callback is implemented, continueCommissioningDevice on MTRDeviceController is expected to be called if commisioning should continue. This allows the delegate to stop commissioning after examining the device info (DAC, PAI, CD).

Parameters:: controller - Controller corresponding to the commissioning process; opaqueDeviceHandle - Handle of device being commissioned; attestationDeviceInfo - Attestation information for the device; error - NSError representing the error code on attestation failure. Nil if success. API-Since: 16.4
