What does this implement/fix? Explain your changes.

This Pull request adds metadata testing for models and data modules for ptf-v2. I have added ConfigBase for the EncoderDecoderTimeSeriesDataModule and the TslibDataModule. Added new classes specific to each of data modules like for models using EncoderDecoderTimeSeriesDataModule I added EncoderDecoderConfigBase and for TslibDataModule I added TslibConfigBase

What should a reviewer concentrate their feedback on?

Thanks, interesting idea!

I am a bit confused about the logic here. I assume that you intend the new test test_d2_metadata to retrieve the new classes that you added, but this will not happen? Since the object_pkg variable will be, for instance, TimeXer_pkg_v2, but that class will never have the check method?

Design-wise, I think the best place to locate the checker method is imo not the model package class, but the D2 layer data class that produces the metadata?
