app/vmselect/prometheus: reduce the default value for -search.maxSeries from 100k to 30k
...
Production experience shows that 100k is too big for /api/v1/series .
It leads to increased CPU usage when Grafana queries /api/v1/series over VictoriaMetrics
with big number of time series during auto-completion and when modifying template variables.

lib/storage: return marshaled metric names from SearchMetricNames
...
Previously SearchMetricNames was returning unmarshaled metric names.
This wasn't great for vmstorage, which should spend additional CPU time
for marshaling the metric names before sending them to vmselect.
While at it, remove possible duplicate metric names, which could occur when
multiple samples for new time series are ingested via concurrent requests.
Also sort the metric names before returning them to the client.
This simplifies debugging of the returned metric names across repeated requests to /api/v1/series

vmselect: limit end
param max value by 2d in future ( #2729 )
...
* vmselect: limit `end` param max value by 2d in future
The change is applied only to service handlers like `/labels` or `/series`
and limits the `end` param by max value <= now() + 2 days. The same limit
is applied for the ingested data, so no reason to allow to request data
in future far than that.
The change is also needed for corner cases like https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2669
where too high `end` value triggers inefficient global index search.

vmselect: update vm_request_duration_seconds
value when request fails ( #1537 )
...
Before, metric `vm_request_duration_seconds` was update only on successful
attempts which could be misleading. For example, timeout errors on netstorage
request may be not accounted in the metric and won't be visible on dashboards.
Using `defer` statement to update the metric after query arguments validation
may improve the situation.
