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.

lib/{storage,mergeset}: merge tag->metricID rows into tag->metricIDs rows for common tag values
...
This should improve lookup performance if the same `label=value` pair exists
in big number of time series.
This should also reduce memory usage for mergeset data cache, since `tag->metricIDs` rows
occupy less space than the original `tag->metricID` rows.
