Responses swallowed when there's an unmarshaling error

[KirkEasterson]

Problem: If a response results in an error when being unmarshaled, the response is lost. This makes it impossible to differentiate a 200 response from a 400 response.

This code highlights the issue. If I receive an unmarshaling error, I don't know if the fault was mine or not.

Suggested fix: Wrap the err with content included, or use some structured error that contains more information about this issue.

I can work on this, but how to handle this case should be decided by more than just me.

Hi @KirkEasterson we generate the API based on this repo: https://github.com/commercetools/rmf-codegen. If you feel up to it you can make the changes there.

I will be back next month and can pick this one up then also.
