lib/storage: change default value for maxLabelValueLen to 1024 ()
* It must reduce memory usage for misbehaving clients. Since
VictoriaMetrics stores sparse index inmemory.
* Reduce disk space usage for indexdb.
* Prevent possible indexDB items drops.
* It may trigger slow insert and new timeseries registration due to
default value for flag change

follow-up for c6c5a5a186 ()
* adds datadog extensions for statsd:
  - multiple packed values (v1.1)
  - additional types distribution, histogram

* adds type check and append metric type to the labels with special tag
name `__statsd_metric_type__`. It simplifies streaming aggregation
config.

* remove statsd support from cluster, since cluster doesn't support
stream aggregation.

Statsd protocol compatibility ()
In this PR I added compatibility with [statsd
protocol](https://github.com/b/statsd_spec) with tags to be able to send
metrics directly from statsd clients to vmagent or directly to VM.
For example its compatible with
[statsd-instrument](https://github.com/Shopify/statsd-instrument) and
[dogstatsd-ruby](https://github.com/DataDog/dogstatsd-ruby) gems

docs: removed code-style highlighting for commanad-line flags of VM components ()
Using `sh` or `console` formatting doesn't do word-breaking on render. This makes flags description
harder to read, as users need to scroll the web page horizontally.
Removing the formatting renders the description with normal word-breaking.

Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com>

* lib/storage: consistently use MaxTimestamp to determine deduplication/downsampling rules

Using MinTimestamp leads to applying downsampling to parts which are only partially covered by downsampling rule.
For example, partition covers range [1000-2000]. At t=2100 and rule offset 500 data with t=2100-500 => 1600 must be downsampled. The range check against MinTimestamp evaluates to true even though partition contains range which must not be downsampled - [1600:2000].

Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com>

* Follow-up

- Apply the first matching downsampling period if multiple filters match the given time series.
  This allows fine-tuning the downsampling config for the specific needs.
- Take into account downsampling filters during search queries.
- Reduce the difference between community and enterprise branches. This should simplify further maintenance of these branches.
- Properly parse series filters with colons inside them.
- Document the feature at docs/CHANGELOG.md.
