docs: use persistent links to Grafana dashboards 
These links do not depend on the dashboard name, so they do not break after the renaming of the dashboard.

all: allow dynamically reading *AuthKey flag values from files and urls 
Examples:

1) -metricsAuthKey=file:///abs/path/to/file - reads flag value from the given absolute filepath
2) -metricsAuthKey=file://./relative/path/to/file - reads flag value from the given relative filepath
3) -metricsAuthKey=http://some-host/some/path?query_arg=abc - reads flag value from the given url

The flag value is automatically updated when the file contents changes.

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.

app/{vminsert,vmagent}: preliminary support for /api/v2/series ingestion from new versions of DataDog Agent 
This commit adds only JSON support - https://docs.datadoghq.com/api/latest/metrics/#submit-metrics ,
while recent versions of DataDog Agent send data to /api/v2/series in undocumented Protobuf format.
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.

The https://github.com/VictoriaMetrics/VictoriaMetrics/releases link may show non-latest
releases at the top, such as LTS releases or VictoriaLogs releases.
So it is better to use https://github.com/VictoriaMetrics/VictoriaMetrics/releases/latest link,
which always redirect to the latest available release of VictoriaMetrics.
