Fabian Reinartz 3f72d5d027 Fix last timestamp initialization 
This initializes the chunkDesc's last timestamp to the minimum
value so initial samples with a timestamp of 0 (e.g. in tests)
are not accidentally dropped.

Fabian Reinartz 5d75a3dc7b Add basic compaction 
This adds a basic compactor that will merge two persisted blocks into
one. It simply fully rewrites the index and concatenates the chunk
lists.

It just writes into the current working dir and doesn't properly handle
which blocks to compact for now.

Fabian Reinartz c00d17e691 Modify IndexReader API to accomodate compaction 
This changes the IndexReader API to expose plain labels
and chunk meta information instead of a Series interface.
Dropping of irrelevant chunks is moved into the querier.

A LabelIndices method is added to query for existing label
value indices.

Fabian Reinartz b08f82fa4e Pre-select relevant chunks on series access. 
This adds interval metadata to indexed chunks. The queried interval
is used to filter chunks when queried from the index to save
unnecessary accesses of the chunks file.

This is especially relevant for series that come and go often and larger
files.
