lib/backup/s3remote: add retryer configuration (#6747)
### Describe Your Changes

This helps to improve reliability of performing backups in environments
with unreliable connection and tolerate temporary errors at S3 provider
side.

See: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6732

Default retry timeout is up to 3 minutes to make this consistent with
the same configuration for GCS:
a05317f61f/lib/backup/gcsremote/gcs.go (L70-L76)

lib/bytesutil: smooth buffer growth rate (#6761)
Before, buffer growth was always x2 of its size, which could lead to
excessive memory usage when processing big amount of data.
For example, scraping a target with hundreds of MBs in response could
result into hih memory spikes in vmagent because buffer has to double
its size to fit the response. See
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6759

The change smoothes out the growth rate, trading higher allocation rate
for lower mem usage at certain conditions.

app/vmselect/graphite: respect denyPartialResponse for graphite requests (#6748)
VM has different responses to equivalent queries for MetricsQL and
GraphiteQL in case of failed access to one of vmstorage node of the
cluster vmstorage nodes. For GraphiteQL, the denyPartialResponse feature
is not used, it is always true, which is not always correct (depending
on the configuration).

In the PR I have removed the hardcoded denyPartialResponse for
GraphiteQL, just like MetricsQL does.

Revert "refactor(vmstorage): Refactor the code to reduce the time complexity of MustAddRows and improve readability (#6629)"
This reverts commit e280d90e9a.

Reason for revert: the updated code doesn't improve the performance of table.MustAddRows for the typical case
when rows contain timestamps belonging to ptws[0].

The performance may be improved in theory for the case when all the rows belong to partiton other than ptws[0],
but this partition is automatically moved to ptws[0] by the code at lines
6aad1d43e9/lib/storage/table.go (L287-L298) ,
so the next time the typical case will work.

Also the updated code makes the code harder to follow, since it introduces an additional level of indirection
with non-trivial semantics inside table.MustAddRows - the partition.TimeRangeInPartition() function.
This function needs to be inspected and understood when reading the code at table.MustAddRows().
This function depends on minTsInRows and maxTsInRows vars, which are defined and initialized
many lines above the partition.TimeRangeInPartition() call. This complicates reading and understanding
the code even more.

The previous code was using clearer loop over rows with the clear call to partition.HasTimestamp()
for every timestamp in the row. The partition.HasTimestamp() call is used in the table.MustAddRows()
function multiple times. This makes the use of partition.HasTimestamp() call more consistent,
easier to understand and easier to maintain comparing to the mix of partition.HasTimestamp() and partition.TimeRangeInPartition()
calls.

Aslo, there is no need in documenting some hardcore software engineering refactoring at docs/CHANGLELOG.md,
since the docs/CHANGELOG.md is intended for VictoriaMetrics users, who may not know software engineering.
The docs/CHANGELOG.md must document user-visible changes, and the docs must be concise and clear for VictoriaMetrics users.
See https://docs.victoriametrics.com/contributing/#pull-request-checklist for more details.

docs/anomaly-detection: return back absolute links instead of relative links after ce4cc4cbb2
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6677

Relative links in docs are much harder to maintain in consistent state comparing to absolute links:

- It is non-trivial to figure out the proper relative link path when creating and editing docs.
- Relative links break after moving the doc files to another paths, and it is non-trivial
  to figure which links are broken after that.

  since it is documented and expected that all the Makefile commands are run from the repository root.

- Use `docker --rm` for running Docker container with local docs server, so it is automatically
  removed after pressing `Ctrl+C`. This makes the container cleanup automatic.

- Relative links break after moving the doc files to another paths, and it is non-trivial

- The updated relative links do not work properly right now in the docs.
  For example, the https://docs.victoriametrics.com/victorialogs/quickstart.md#building-from-source-code

- Relative links break after moving the doc files to another paths, and it is non-trivial
  to figure which links are broken after that.
- The updated relative links do not work properly right now in the docs.
  For example, the https://docs.victoriametrics.com/victorialogs/quickstart.md#building-from-source-code
  link at https://docs.victoriametrics.com/victorialogs/changelog/ leads to 404 page.

Revert "fixed victorialogs relative links (#6693)"
This reverts commit 683a69d53d.

Reason for revert: relative links in docs are much harder to maintain in consistent state
comparing to absolute links:

- It is non-trivial to figure out the proper relative link path when creating and editing docs.
- Relative links break after moving the doc files to another paths, and it is non-trivial
  to figure which links are broken after that.
- The updated relative links do not work properly right now in the docs.
  For example, the https://docs.victoriametrics.com/victorialogs/quickstart.md#building-from-source-code
  link at https://docs.victoriametrics.com/victorialogs/changelog/ leads to 404 page.
