- add a separate index cache for searches which might read through large
amounts of random entries. Primary use-case for this is retention and
downsampling filters, when applying filters background merge needs to
fetch large amount of random entries which pollutes an index cache.
Using different caches allows to reduce effect on memory usage and cache
efficiency of the main cache while still having high cache hit rate. A
separate cache size is 5% of allowed memory.
- reduce size of indexdb/dataBlocks cache in order to free memory for
new sparse cache. Reduced size by 5% and moved this to a separate cache.
- add a separate metricName search which does not cache metric names -
this is needed in order to allow disabling metric name caching when
applying downsampling/retention filters. Applying filters during
background merge accesses random entries, this fills up cache and does
not provide an actual improvement due to random access nature.

Auto-adjust `-remoteWrite.concurrency` cmd-line flags with the number of
available CPU cores in the same way as vmagent does. With this change
the default behavior of vmalert in high-loaded installation should
become more resilient. This change also reduces
`-remoteWrite.flushInterval` from `5s` to `2s` to provide better data
freshness.

### Describe Your Changes
If a dict flag has only one value without a prefix it is supposed to
replace default value.
Previously, when flag was set to `-flag=2` and the default value in
`NewDictInt` was set to 1 the resulting value for any `flag.Get()` call
would be 1 which is not expected.
This commit updates default value for the flag in case there is only one
entry for flag and the entry is a number without a key.
This affects cluster version and specifically `replicationFactor` flag
usage with vmstorage [node
groups](https://docs.victoriametrics.com/cluster-victoriametrics/#vmstorage-groups-at-vmselect).
Previously, the following configuration would effectively be ignored:
```
/path/to/vmselect \
-replicationFactor=2 \
-storageNode=g1/host1,g1/host2,g1/host3 \
-storageNode=g2/host4,g2/host5,g2/host6 \
-storageNode=g3/host7,g3/host8,g3/host9
```
Changes from this PR will force default value for `replicationFactor`
flag to be set to `2` which is expected as the result of this
configuration.

After adding multitenant query feature at v1.104.0, searchQuery wasn't
properly unmarshalled at bottom vmselect in multi-level cluster setup.
It resulted into empty query responses.
This commit adds fallback to Unmarshal method of SearchQuery to fill
TenantTokens. It allows to properly execute search requests
at vmselect side.

### Describe Your Changes
Currently, vmagent always uses a separate `http.Client` for every group
watcher in Kubernetes SD. With a high number of group watchers this
leads to large amount of opened connections.
This PR adds 2 changes to address this:
- re-use of existing `http.Client` - in case `http.Client` is connecting
to the same API server and uses the same parameters it will be re-used
between group watchers
- HTTP2 support - this allows to reuse connections more efficiently due
to ability of using streaming via existing connections.

When ingesting samples with the same labels(duplicated samples or
samples with the same labels after `by` or `without` options). They
could register different entries for the same labelset in
LabelsCompressor.
For example, both index 99 and 100 can be assigned to label `foo=1` in
two concurrent pushes. Then due to differing label indexes in encoded
keys, the samples will appear as distinct in aggrState, resulting in
duplicated results after decompressing the label indexes.
fbde238cdc/lib/streamaggr/streamaggr.go (L933)
In this pull request, since we need to store `idxToLabel` first to
ensure the idx can be searched after `lc.labelToIdxStore`,
the `lc.idxToLabel` still could contain a duplicated entries
[100]="foo=1". But given the low likelihood of this issue and the size
of idxToLabel, it should be fine.
Previous commit 201fd6de1e removed
trailing space trim from data read from file. But common practice is to
remove such trailing space. And it leaded to the authorization errors
for the major group of users.
In first place, this change must help to mitigate an issue with
kubernetes. When authorization information was read from Secret content.
Changes to the operator was made to mitigate such problem at commit
1cf64358c8
We could introduce later optional flag for VictoriaMetrics to disable
trim space behavior.
