99004a6a40 app/vmselect/netstorage: unpack time series data in mostly local big chunks

49bf3abf67 app/vmselect: follow-up for 626073bca8 
* Rename -search.maxMetricsPointSearch to -search.maxSamplesPerQuery, so it is more consistent with the existing -search.maxSamplesPerSeries
* Move the -search.maxSamplesPerQuery from vmstorage to vmselect, so it could effectively limit the number of raw samples obtained from all the vmstorage nodes
* Document the -search.maxSamplesPerQuery in docs/CHANGELOG.md

9add9d86a6 app/vmselect/promql: duration handling improvements in MetricsQL queries 
- Support durations anywhere in MetricsQL queries. E.g. sum_over_time(m[1h])/1h is equivalent to sum_over_time(m[1h])/3600
- Support durations without suffix. E.g. rate(m[300]) is equivalent to rate(m[5m])

4b25e627f8 lib/workingsetcache: properly switch to whole mode 
Previously the switch from `split` to `whole` mode had been performed too early,
e.g. when the current cache size became bigger than 1/4 of the allowed cache size.

Now it is performed when the current cache size becomes bigger than 1/2 of the allowed cache size.

This change can reduce memory usage for data ingestion path when big number of active time series are ingested.

b133de1e37 lib/storage: move deletedMetricIDs set from indexDB to Storage 
This makes consitent the list of deleted metricIDs when it is used from both the current indexDB and the previous indexDB (aka extDB).
This should fix the issue, which could lead to storing new samples under deleted metricIDs after indexDB rotation.
See more details at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1347#issuecomment-861232136 .

Thanks to @tangqipengleoo for the initial analysis and the pull request - https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 .

This commit resolves the issue in more generic way compared to https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 .

The downside of the commit is the deletedMetricIDs set isn't cleaned from the metricIDs outside the retention. It needs app restart.
This should be OK in most cases.

ec6becd3f5 lib/httpserver: stop the process on panics in request handlers 
Panics may leave the process in inconsistent state. That's why it is better to stop the process after the panic
instead of recovering from the panic. Unfortunately, the standard net/http.Server recovers panics in request handlers.
See https://github.com/golang/go/issues/16542 . That's lib/httpserver must stop the process on itself after the panic.
