(cherry picked from commit 11b03d9fc8)
- Consistently return the first `limit` log entries if the total size of found log entries doesn't exceed 1Mb.
See app/vlselect/logsql/sort_writer.go . Previously random log entries could be returned with each request.
- Document the change at docs/VictoriaLogs/CHANGELOG.md
- Document the `limit` query arg at docs/VictoriaLogs/querying/README.md
- Make the change less intrusive.

* app/vmauth: properly release memory during config reload
previously metrics package hold a refrence for channels for users concurrent requests.
it case of churn at `name` field of users configuration, new metric was created. But previous one wasn't deleted.
It prevented full parsed configuration from being garbace collected.
now all config related metrics are bound to corresponding metrics.Set and unregistered during config reload process.
It also must fix an issue with incorrect values for current concurrent user requests

Closing client connections every 2 minutes doesn't help load balancing -
this just leads to "jumpy" connections between multiple backend servers,
e.g. the load isn't spread evenly among backend servers, and instead jumps
between the servers every 2 minutes.
It is still possible periodically closing client connections by specifying non-zero -http.connTimeout command-line flag.
This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1304#issuecomment-1636997037
This is a follow-up for d387da142e
This panic could occur when samples with too long label values are ingested into VictoriaMetrics.
This could result in too long fistItem and commonPrefix values at blockHeader (up to 64kb each).
This may inflate the maximum index block size by 4 * maxIndexBlockSize.
* add more details to changelog
* simplify panels description
* remove capacity planning recommendation, as it proves it incompetent

During background downsampling, rate(vm_deduplicated_samples_total{type="merge"}) could be much bigger than
rate(vm_rows_added_to_storage_total) and it could last quite some time,
which causes negative values of Storage full ETA and confuses users, see playground.
Instead of trying to get more accurate results during downsampling, I think it's ok to ignore
vm_deduplicated_samples_total at all, it's more reasonable to see Storage full ETA increase after downsampling.

changes(), increases_over_time() and resets() shouldn't take into account
value changes, which may occur because of precision errors.
The maximum guaranteed precision for raw samples stored in VictoriaMetrics is 12 decimal digits.
So do not count relative changes for values if they are smaller than 1e-12 comparing to the value.
