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.

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.

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.
