Consumer Resume/Pause Propagating Errors

[anna-fry]

Description

Reading the documentation for the resume and pause functions for consumers in librdkafka here, it seems as though the resume and pause functions that this library wraps always returns a NO_ERROR and instead adds the error from resuming/pausing the consumer to the partitions list passed to the function. However it does not seem as though the implementation of the pause/resume function looks for the errors within the partitions list when considering whether or not to return an error. Is this a correct understanding of the library's implementation? Is there a way to propagate the error added to the partition list in librdkafka to users of this library?

It doesn't look like it. Fixing this will be a breaking API change I think. That's awkward.
