Fabian Reinartz 96d7f540d4 Persist series without allocating the full set 
Change index persistence for series to not be accumulated in memory
before being written as one large batch. `Labels` and `ChunkMeta`
objects are reused.
This cuts down memory spikes during compaction of multiple blocks
significantly.

As part of the the Index{Reader,Writer} now have an explicit notion of
symbols and series must be inserted in order.

This removes the flag from the label value index and serializes it using

Fabian Reinartz a8e8903350 Use ChunkMeta references for clarity 
This has been a common source of hard to debug issues. Its a premature

be references in all changed cases.
