547bcdce63 app/vmstorage: enable compression of responses to vmselect by default
This should save vmstorage => vmselect network bandwidth in common case
when recently added data is queried.

d54f5fec0b lib/storage: skip adaptive searching for tag filter matching the minimum number of metrics if the identical previous search didn't found such filter
This should improve speed for searching metrics among high number of time series
with high churn rate like in big Kubernetes clusters with frequent deployments.

5fcdb4a59a app/vminsert: improve handling of unhealthy vmstorage nodes
* Spread load evenly among remaining healthy nodes instead of hammering
  the next node after the unhealthy node.
* Make sure that the packet is flushed to storage node before returning success.
  Previously packets could stay in local buffers and thus lost on connection errors.
* Keep rows in the limited memory when all the storage nodes are unhealthy.

89a113cb5d app/vminsert: really fix #60
ReadLinesBlock may accept dstBuf with non-zero length. In this case the last line without trailing newline isn't read.
Fix this by comparing len(dstBuf) to 0 instead of its original length.

8f4790625d app/vmselect/promql: return the correct time series from quantile
Previously arbitrary time series could be returned from `quantile`
depending on sort order for the last data point in the selected range.

Fix this by returning the calculated time series.

2ff0d595b0 app/vmselect/promql: add -search.disableCache flag for disabling response caching
This may be useful for data back-filling, when the response caching
could interfere badly with newly added data points with timestamps
in the past.
