0efd37cec1 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 56b6b893ce .
This resulted in increased write disk IO usage on systems with many cpu cores
as described at https://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

cf506e300d Change default value of '-remoteWrite.queues' to cgroup.AvailableCPUs * 2 (#1385)
* 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.

* Update README and flag description

a15c947045 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.

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.

0672cfffa2 app/vmauth: properly handle http.ErrAbortHandler panic
This panic can be raised by the reverseProxy on aborted request to the backend.
So handle it (e.g. suppress) at reverseProxy.ServeHTTP call.

Do not suppress the panic at lib/httpserver generic HTTP handler,
since it may result in an inconsistent state left after the panicking handler.

* vmalert: support rules backfilling (aka `replay`)

vmalert can `replay` configured rules in the past
and backfill results via remote write protocol.
It supports MetricsQL/PromQL storage as data source,
and can backfill data to remote write compatible
storage.

Supports recording and alerting rules `replay`. See more
details in README.
