This handler will instruct search engines that indexing is not allowed for the content exposed to the internet. This should help to address issues like #4128 when instances are exposed to the internet without authentication.
"How do We Keep Metrics for a Long Time in VictoriaMetrics" article is referenced twice in "Third-party articles and slides about VictoriaMetrics" section
Improperly configured -bigMergeConcurrency command-line flag usually leads to uncontrolled
growth of unmerged parts, which, in turn, increases CPU usage and query durations.
So it is better deprecating this flag. In rare cases -smallMergeConcurrency command-line flag
can be used instead for controlling the concurrency of background merges.
This makes it easier to understand exact point in time which is included in this backup.
