Fabian Reinartz a317f252b9 Expose series references to clients
This exposes a reference number of a series represented by a label set
to clients.
Subsequent samples can be directly added via the reference rather than
repeatedly passing in the full labels. This drasitcally speeds up the
append process.

The appender chain uses different sections of the reference number for
assignment to child appenders and invalidating reference numbers as
necessary.

Clients can either pass out reference numbers themselves or have their
own optimized lookup, i.e. by directly associating unparsed metric
descriptors strings with reference numbers.

Fabian Reinartz 80affd98a8 Add barrier to benchmark writer
This adds a barrier to avoid issues with unfair goroutine scheduling
that causes some fake scrapers to run away from the other ones.

Fabian Reinartz 300f4e2abf 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

Fabian Reinartz c61b310210 Naive size-based compaction
This adds naive compaction that tries to compact three
blocks of roughly equal size.
It decides based on samples present in a block and has no
safety measures considering the actual file size.

Fabian Reinartz e561c91d53 Implement proper buffered iterator
This adds a proper duration based lookback buffer for series iterators
to allow advancing sequentially while remaining able to calculate time
aggregating functions such as `rate` backwards.

It uses an array ring buffer to minimize heap allocations for
potentially hundreds of thousands of series for a single query.
