lib/{mergeset,storage}: reduce the number of fsync calls on data ingestion path on systems with many cpu cores
...
VictoriaMetrics maintains a buffer per CPU core for the ingested data. These buffers are flushed to disk every second.
These buffers are flushed to disk in parallel starting from the commit 56b6b893cehttps://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338#issuecomment-863046999 .
This commit merges the per-CPU buffers into bigger in-memory buffers before flushing them to disk.
This should reduce the rate of fsync syscalls and, consequently, the write disk IO on systems with many CPU cores.
This should help https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338

* Change default value of '-remoteWrite.queues' to cgroup.AvailableCPUS() * 2 to reduce scrape interval
Default value of vmagent option '-remotewrite.queues' is 4 and default
size of vmagent ScheudleUnmarshalWorkers is number of CPUs, when available
CPUs is much greater than 4, e.g 32, worker are competing push queues
which will increase scrape interval and may cause scrape timeout.

promql: fix increase_pure calculation for cases with stale series ( #1381 )
...
Due to staleness handling, increase_pure were using incorrect previous value
during calculation in cases where series disappears for period longer
than staleness period and then returns back. The fix suppose to account
for a real datapoint value before staleness takes place. The fix should
remove unexpected spikes while using `increase_pure` for staled series.

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.
