docs: follow-up for ac9c2a796f
Remove description for -search.maxExportDuration and -search.maxStatusRequestDuration command-line flags
from the 'Resource usage limits' chapter, since these flags are rarely used for limiting resource usage
and they are already documented in the 'List of command-line flags' chapter.

* lib/storage/downsampling: update log messages for final dedup

Properly specify a reason of re-running deduplication for partition.

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.

app/vmselect: add -search.maxLabelsAPIDuration and -search.maxLabelsAPISeries options for fine-tuning CPU and RAM usage for /api/v1/series , /api/v1/labels and /api/v1/label/.../values
This commit returns back limits for these endpoints, which have been removed at 5d66ee88bd ,
since it has been appeared that missing limits result in high CPU usage, while the introduced concurrency limiter
results in failed lightweight requests to these endpoints because of timeout when heavyweight requests are executed.

docs: remove slug from Grafana dashboard URLs
Each Grafana dashboard has unique ID which can be used to fetch the dashboard
from grafana.com: https://grafana.com/grafana/dashboards/11176
The same dashboard can be accessed via URL with slug: https://grafana.com/grafana/dashboards/11176-victoriametrics-cluster/
But using slug implies that any change to dashboard name will break the link.
So it is better to just use ID, so the dashboard URL will never break.

The support for this format will be added later.

lib/protoparser: decrease import.maxLineLen from 100MB to 10MB (#5364)
Tests showed that importing a single line with 70MB size takes 5.3GiB
RSS memory for VictoriaMetrics single-node.
In the scenario when user exports and imports data from one VM to another,
it could possibly lead to OOM exception for destination VM.

Importing a single line with 16MB size taks 1.3GiB RSS memory.
Hence, the limit for `import.maxLineLen` was decreased from 100MB to 10MB
to improve reliability of VictoriaMetrics during imports.

lib/blockcache: do not cache entries, which were attempted to be accessed 1 or 2 times
Previously entries which were accessed only 1 time weren't cached.
It has been appeared that some rarely executed heavy queries may read indexdb block twice
in a row instead of once. There is no need in caching such a block then.
This change should eliminate cache size spikes for indexdb/dataBlocks when such heavy queries are executed.

Expose -blockcache.missesBeforeCaching command-line flag, which can be used for fine-tuning
the number of cache misses needed before storing the block in the caching.
