a9cfca6a72 README.md: add max_shards: 100 to the recommended Prometheus config
Prometheus establishes a connection per shard in remote_write config.
By default it establishes up to 1000 connections to remote storage (max_shards: 1000).
This is quite big, so set `max_shards: 100` in the recommmended Prometheus config.

d2c801029b lib/storage: persist metric ids for the current and the previous hour on graceful shutdown
This should improve performance after restart when the db contains a lot of time series
with high time series churn (i.e. metrics from Kubernetes with many pods and frequent deployments)

f4252f87e6 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.
