Mauro Stettler	0df3489275	Write chunks via queue, predicting the refs (#10051) ... * Write chunks via queue, predicting the refs Our load tests have shown that there is a latency spike in the remote write handler whenever the head chunks need to be written, because chunkDiskMapper.WriteChunk() blocks until the chunks are written to disk. This adds a queue to the chunk disk mapper which makes the WriteChunk() method non-blocking unless the queue is full. Reads can still be served from the queue.
