### Describe Your Changes
Currently if multiple msgFields are present in a log row it's not
obvious which field is selected as a _msg field. With this PR and order
of msgfield values defined either via headers or query arg params
defines a priority of these values

### Describe Your Changes
- datadog /api/v2/logs api supports message field in json format, which
is not documented and is used by serverless extension. This PR allows
message field to be both string and object type. Also added support of
not documented timestamp field
- added `-datadog.streamFields` and `-datadog.ignoreFields` flags to
configure default stream fields for datadog logs, where there's no
alternative option to pass extra headers and query args
- added ingest `max` and `min` values of data, which are ingested using
`datadogsketches` API, which is also actively used by serverless
extensions
- use default `.` separator instead of `_` for sketches metric names
until metrics are not sanitized
This should prevent from excess usage of CPU, RAM and other resources when too many logs
are passed to 'stream_context' pipe.
It is expected that 'stream_context' pipe results are investigated by humans, who cannot inspect
surrounding logs for millions of initial logs. That's why it is OK to limit the number of logs
and/or log streams, which can be passed to 'stream_context' pipe.

While at it, reduce memory allocations at Storage.getFieldValuesNoHits and make it more scalable on multi-CPU systems.
This improves performance of in(<query>) filter when the <query> returns big number of values.
Use chunked allocator in order to reduce memory allocations. It allocates objects from slices of up to 64Kb size.
This improves performance for `stats` and `top` pipes by up to 2x when they are applied to big number of `by (...)` groups.
Also parallelize execution of `count_uniq`, `count_uniq_hash` and `uniq_values` stats functions,
so they are executed faster on hosts with many CPU cores when applied to fields with big number
of unique values.
The commit 4599429f51 improperly set br.cs to nil,
while it should set br.bs to nil instead. This resulted in excess memory allocations
at br.csInit() and br.csInitFast().

Historically some of VictoriaMetrics components were optimized for the low rate of memory allocations.
These are: vmagent, single-node VictoriaMetrics and vmstorage. These components benefit from the low
GOGC value, since this allow reducing their memory usage in steady state on typical workloads.
Other VictoriaMetrics components aren't optimized for the reduced rate of memory allocations.
This results in the increased CPU usage spent on garbage collection (GC) in these components,
since it must be triggered at higher rate. See https://tip.golang.org/doc/gc-guide#GOGC for details.
These components do not use too much memory, so it is OK increasing the GOGC for these components
from 30 to 100 - this won't affect the most users.
Keep GOGC to 30 only for vmagent, single-node VictoriaMetrics and vmstorage components.
See 077193d87c and 54b9e1d3cb .

Numeric fields can be stored as const values in the block of logs. In this case the `sort` pipe
was incorrectly comparing such values as strings instead of numbers. This results in incorrect
sort results. For example, 123 was smaller than 2. Fix this by removing the incorrect case
for comparing const fields.
While at it, replace lessString() with strings.LessNatural() in the sortBlockLess.
This improves sorting performance a bit, since the sortBlockLess function already tried
comparing numeric values, and it doesn't need to spend CPU time on such a comparison again inside lessString() call.
The commit 42c9183281 wasn't correct by replacing strings.LessNatural() with lessString()
inside the sortBlockLess() function.
* simplify wording
* update styles
* remove extra info about go application details. The details are likely
not needed and we didn't have details for rolling-dice app anyway. So
keep it simple for consstency and brevity.
* update navigation for simplicity sake
* fix typos

vmauth started to use request.Host after commit
f4776fec1b for`src_hosts` routing rules.
This commit adds http.Request.Host to the debugInfo output in order to
be consistent with routing logic.

Regression was introduced at 564e6ea024
after implementing:
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6928
ctx.Labels array could be incorrectly updated and changes to it after
relabeling rules can be lost.
E.g. ctx.Labels passed to WriteDataPoint function as slice copy, but
results of relabeling only changed an actual slice at ctx.Labels.
This commit replaces implicit relabeling call with explicit
`TryPrepareLabels` function.
It also reduces code diffs with cluster version and adds integration tests
