cdc372bb98 app/vmselect: add -search.noStaleMarkers command-line flag for disabling stale markers handling in queries 
This option allows reducing CPU usage a bit when VictoriaMetrics is used
for collecting and processing non-Prometheus data. For example, InfluxDB line protocol, Graphite, OpenTSDB, CSV, etc.

226143f31b lib/promscrape: add ability to disable sending Prometheus staleness markers with -promscrape.disableStaleMarkers command-line flag 
This option can be useful when vmagent consumes too much additional memory
for staleness markers functionality and when staleness markers aren't needed.

8f973e34fb 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.

84fb59b0ba 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.
