  1. Fixes race conditions in the batch iterator. 

    We should never advance an iterator in parallel. Unfortunately before the code was building iterators while advancing previous one, building iterator can advance iterator and thus creates a race condition. This changeset make sure we only fetch chunks in advance and build iterator and iterate over them in sequence.

Also add support for labels in the cacheIterator which is required for logqlv2.
