Do a batch inference with custom docker

### Describe your suggestion

How is possible to start a batch inference using a custom docker in SDK2? All samples using a custom docker are in SDK1 and none of them uses batch.

### Additional details

_No response_

Compare the existing SDK1 custom Docker samples with the SDK2 examples and locate the batch inference entry point. Add a runnable SDK2 example showing batch inference with a custom Docker image; done means the example is complete and can be tested like the repository's other examples.
