Use separate lock for series creation

This uses the head block's own lock to only lock if new series were
encountered.
In the general append case we just need to hold a

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.

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.

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.

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.
