### Describe Your Changes
**Added ability to hide the hits chart**
- Users can now hide or show the hits chart by clicking the "eye" icon
located in the upper-right corner of the chart.
- When the chart is hidden, it will stop sending requests to
`/select/logsql/hits`.
- Upon displaying the chart again, it will automatically refresh. If a
relative time range is set, the chart will update according to the time
period of the logs currently being displayed.
**Hits chart visible:**
**Hits chart hidden:**

### 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.

It has been appeared that VictoriaLogs is frequently used for collecting logs with tens of fields.
For example, standard Kuberntes setup on top of Filebeat generates more than 20 fields per each log.
Such logs are also known as "wide events".
The previous storage format was optimized for logs with a few fields. When at least a single field
was referenced in the query, then the all the meta-information about all the log fields was unpacked
and parsed per each scanned block during the query. This could require a lot of additional disk IO
and CPU time when logs contain many fields. Resolve this issue by providing an (field -> metainfo_offset)
index per each field in every data block. This index allows reading and extracting only the needed
metainfo for fields used in the query. This index is stored in columnsHeaderIndexFilename ( columns_header_index.bin ).
This allows increasing performance for queries over wide events by 10x and more.
Another issue was that the data for bloom filters and field values across all the log fields except of _msg
was intermixed in two files - fieldBloomFilename ( field_bloom.bin ) and fieldValuesFilename ( field_values.bin ).
This could result in huge disk read IO overhead when some small field was referred in the query,
since the Operating System usually reads more data than requested. It reads the data from disk
in at least 4KiB blocks (usually the block size is much bigger in the range 64KiB - 512KiB).
So, if 512-byte bloom filter or values' block is read from the file, then the Operating System
reads up to 512KiB of data from disk, which results in 1000x disk read IO overhead. This overhead isn't visible
for recently accessed data, since this data is usually stored in RAM (aka Operating System page cache),
but this overhead may become very annoying when performing the query over large volumes of data
which isn't present in OS page cache.
The solution for this issue is to split bloom filters and field values across multiple shards.
This reduces the worst-case disk read IO overhead by at least Nx where N is the number of shards,
while the disk read IO overhead is completely removed in best case when the number of columns doesn't exceed N.
Currently the number of shards is 8 - see bloomValuesShardsCount . This solution increases
performance for queries over large volumes of newly ingested data by up to 1000x.
The new storage format is versioned as v1, while the old storage format is version as v0.
It is stored in the partHeader.FormatVersion.
Parts with the old storage format are converted into parts with the new storage format during background merge.
It is possible to force merge by querying /internal/force_merge HTTP endpoint - see https://docs.victoriametrics.com/victorialogs/#forced-merge .
Previously it was incorrectly used append for pre-allocated slice of labels.
This commit fixes slice append by allocating zero length slice with needed capacity.

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

### 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.
