* Added Chunk versions of all iterating methods. It all starts in Querier/ChunkQuerier. The plan is that
Storage will implement both chunked and samples.
* Added Seek to chunks.Iterator interface for iterating over chunks.
* Mock, NewTestSeries, SampleSeriesIterator and ChunkSeriesIterator are now available from storage package and reuses instead of
being recreated in many places. NewConcreteSeries was created to replace concreteSeries.
* NewMergeChunkQuerier was added; Both this and NewMergeQuerier are now using generigMergeQuerier to share the code. Generic code was added.
* Both Compactor and block Querier use *exactly* the same iterators. (blockChunkSeriesSet).
* Added some TODO for further simplifications in next PRs.
