vmalert: add command line flag -notifier.headers (#6751)
to allow configuring additional headers in each request to the
corresponding notifier.
Other flags like `-datasource.headers`, `-remoteWrite.headers` already
use `^^` as delimiter, it's consistent to use it in `-notifier.headers`
as well.

related https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3260
vmalert can integrate with alertmanager that supports multi-tenant by
adding tenantID header`X-Scope-OrgID` in requests.
In multitenancy, vmalert can also filter alerts which send to different
notifier addresses(or with different header settings) using
`alert_relabel_configs`.

app/vminsert: returns back memory optimisation (#6794)
Production workload shows that it's useful optimisation.

Channel based objects pool allows to handle irregural data ingestion
requests and make memory allocations more smooth.
It's improves sync.Pool efficiency, since objects from sync.Pool removed
after 2 GC cycles. With GOGC=30 value, GC runs significantly more often.

vmagent: resolve the issue where usePromCompatibleNaming is not working (#6776)
Describe Your Changes
When I use usePromCompatibleNaming with vmagent to process data that
needs to be formatted from different sources such as InfluxDB, I find
that it doesn’t work

However, it works in vminsert. I found that vminsert uses the
HasRelabeling method to determine whether to relabel.
```go
func HasRelabeling() bool {
	pcs := pcsGlobal.Load()
	return pcs.Len() > 0 || *usePromCompatibleNaming
}
```
in vmagent, the decision to relabel is determined only by
pcsGlobal.Len() > 0. However, in the applyRelabeling method, the
usePromCompatibleNaming logic is also used to determine whether to
relabel in the error handling.
```go
func (rctx *relabelCtx) applyRelabeling(tss []prompbmarshal.TimeSeries, pcs *promrelabel.ParsedConfigs) []prompbmarshal.TimeSeries {
	if pcs.Len() == 0 && !*usePromCompatibleNaming {
		// Nothing to change.
		return tss
	}
```
So I think that the logic for determining whether to relabel in vmagent
is not as expected.

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.

Revert "removed unneeded ref shortcodes, updated VM changelog to use relative markdown links (#6691)"
This reverts commit 2e9b1efeb9.

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.

This is documented at https://docs.victoriametrics.com/#images-in-documentation .

The Request.Body for requests without body can be nil. This could break readTrackingBody.Read() logic,

Fix this by initializing the readTrackingBody.r with zeroReader.

While at it, properly set Host header if it is specified in 'headers' section.
It must be set net/http.Request.Host instead of net/http.Request.Header.Set(),
since the net/http.Client overwrites the Host header with the value from req.Host
before sending the request.

While at it, add tests for requestHandler(). Additional tests for various requestHandler() cases
will be added in future commits.

  in the future, so there is no sense in hiding them under string constants with some other names.

- Refer to https://docs.victoriametrics.com/vmbackup/#providing-credentials-via-env-variables in error messages
  when auth creds are improperly configured. This should simplify figuring out how to fix the error.

- Simplify the code a bit at FS.newClient(), so it is easier to follow it now.
  While at it, remove the check when superflouos environment variables are set, since it is too fragile
  and it looks like it doesn't help properly configuring vmbackup / vmrestore.

- Remove envLookuper indirection - just use 'func(name string) (string, bool)' type inline.
  This simplifies code reading and understanding.

- Split TestFSInit() into TestFSInit_Failure() and TestFSInit_Success(). This simplifies the test code,
  so it should be easier to maintain in the future.

lib/protoparser/graphite: follow-up for 476faf5578
- Clarify the description of -graphite.sanitizeMetricName command-line flag at README.md
- Do not sanitize tag values - only metric names and tag names must be sanitized,
  since they are treated specially by Grafana. Grafana doesn't apply any restrictions on tag values.
- Properly replace more than two consecutive dots with a single dot.
- Disallow unicode letters in metric names and tag names, since neither Prometheus nor Grafana
  do not support them.

Fix inconsistent error handling in Storage.AddRows() (#6583)
`Storage.AddRows()` returns an error only in one case: when
`Storage.updatePerDateData()` fails to unmarshal a `metricNameRaw`. But
the same error is treated as a warning when it happens inside
`Storage.add()` or returned by `Storage.prefillNextIndexDB()`.

This commit fixes this inconsistency by treating the error returned by
`Storage.updatePerDateData()` as a warning as well. As a result
`Storage.add()` does not need a return value anymore and so doesn't
`Storage.AddRows()`.

Additionally, this commit adds a unit test that checks all cases that
result in a row not being added to the storage.

Revert "app/vmauth: reader pool to reduce gc & mem alloc (#6533)"
This reverts commit 4d66e042e3.

Reasons for revert:

- The commit makes unrelated invalid changes to docs/CHANGELOG.md
- The changes at app/vmauth/main.go are too complex. It is better splitting them into two parts:
  - pooling readTrackingBody struct for reducing pressure on GC
  - avoiding to use readTrackingBody when -maxRequestBodySizeToRetry command-line flag is set to 0

Let's make this in the follow-up commits!

lib/promscrape/discovery/yandexcloud: follow-up for 070abe5c71
- Obtain IAM token via GCE-like API instead of Amazon EC2 IMDSv2 API,
  since it looks like IMDBSv2 API isn't supported by Yandex Cloud
  according to https://yandex.cloud/en/docs/security/standard/authentication#aws-token :

  > So far, Yandex Cloud does not support version 2, so it is strongly recommended
  > to technically disable getting a service account token via the Amazon EC2 metadata service.

- Try obtaining IAM token via GCE-like API at first and then fall back to the deprecated Amazon EC2 IMDBSv1.
  This should prevent from auth errors for instances with disabled GCE-like auth API.
  This addresses @ITD27M01 concern at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5513#issuecomment-1867794884

- Make more clear the description of the change at docs/CHANGELOG.md , add reference to the related issue.

P.S. This change wasn't tested in prod because I have no access to Yandex Cloud.
It is recommended to test this change by @ITD27M01 and @vmazgo , who filed
the issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5513
