c8ea697db8 lib/storage: de-duplicate tags in MetricName.sortTags 
Leave only the last tag among tags with duplicate keys. This is needed for reliable addition of extra_labels
during data ingestion. See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1007 for details.

46dba00756 lib/storage: remove stale parts as soon as they go outside the configured retention 
Previously such parts could remain undeleted for long durations until they are merged with other parts.
This should help for `-retentionPeriod` values smaller than one month.

f765985947 lib/fs: replace fs.OpenReaderAt with fs.MustOpenReaderAt 
All the callers for fs.OpenReaderAt expect that the file will be opened.
So it is better to log fatal error inside fs.MustOpenReaderAt instead of leaving this to the caller.

ae91a6883c lib/{storage,mergeset}: clean cached index blocks and inmemory blocks more aggressively
