deployment/dashboards: fix Storage full ETA panels ()
During background downsampling, rate(vm_deduplicated_samples_total{type="merge"}) could be much bigger than 
rate(vm_rows_added_to_storage_total) and it could last quite some time,
 which causes negative values of Storage full ETA and confuses users, see playground.

Instead of trying to get more accurate results during downsampling, I think it's ok to ignore 
vm_deduplicated_samples_total at all, it's more reasonable to see Storage full ETA increase after downsampling.

alerts: simplify aggregation of alerting rules
This is follow-up after
75196d7234

It updates some of the alerting rules to remove unnecessary aggregations.
It keeps aggregations for expressions which are using multiple time series
filters to make sure their label will match.

alerts: move ConcurrentFlushesHitTheLimit alert to health alerts
The `ConcurrentFlushesHitTheLimit` could be related to components like
vminsert, vmstorage, vm-single-node and vmagent. Moving this alert
to the `health` section of alerts will be benefitial for all components
and will remove the duplicates from single/cluster alerts.

docs/Troubleshooting.md: document an additional case, which could result in slow inserts
If `-cacheExpireDuration` is lower than the interval between ingested samples for the same time series,
then vm_slow_row_inserts_total` metric is increased.

lib/writeconcurrencylimiter: improve the logic behind -maxConcurrentInserts limit
Previously the -maxConcurrentInserts was limiting the number of established client connections,
which write data to VictoriaMetrics. Some of these connections could be idle.
Such connections do not consume big amounts of CPU and RAM, so there is a little sense in limiting
the number of such connections. So now the -maxConcurrentInserts command-line option
limits the number of concurrently executed insert requests, not including idle connections.

It is recommended removing -maxConcurrentInserts command-line option, since the default value
for this option should work good for most cases.

alerts: remove show_at label for RequestErrorsToAPI alert ()
Alert `RequestErrorsToAPI` could be permanently triggered due to
mistakes in clients configuration. However, such requests are unlikely
to cause VM health state change. So there is no need in displaying
this alert because there will be no correlation caused by it.

dashboards: update VM single dash ()
The change list is the following:
* bump Grafana version to 9.2.6;
* replace old "Graph" panel with "TimeSeries" panel;
* show % usage of Mem and CPU additionally to of absolute values;
* `Caches` row was removed. All needed info for caches is now part of `Troubleshooting`;
* add Annotations for Alert triggers. Not all alerts are supposed to be displayed
on the dashboard, but only those with label `show_at: dashboard`.

vmagent: expose metric vmagent_remotewrite_queues ()
The new metric `vmagent_remotewrite_queues` exports a static value of
number of configured remote write queus. This metric is useful to
calculate total saturation per each configured URL with given number
of queues. See corresponding changes to vmagent alerts and dashboard.

The new panel `CPU percentage` was added instead if adding a limit

of components each with own limits. The separate panel should provide
a clear display of CPU load.
