0d44e371f3 lib/promscrape: add -promscrape.suppressDuplicateScrapeTargetErrors command-line flag in order to suppress duplicate scrape target errors
Show also original labels for duplicate targets in error message in order to simplify debugging the issue.

Now `/targets` endpoint accepts optional `show_original_labels=1` query arg, which shows original labels for each target.
This may simplify debugging for target relabeling.

fd7dd5064a lib/storage: code cleanup after 10f2eedee0
Remove the code that uses metricIDs caches for the current and the previous hour during metricIDs search,
since this code became unused after implementing per-day inverted index almost a year ago.

While at it, fix a bug, which could prevent from finding time series with names containing dots (aka Graphite-like names
such as `foo.bar.baz`).

eee6f1e56d lib/persistentqueue: make the persistent queue more durable against unclean shutdown (kill -9, OOM, hard reset)
The strategy is:

- Periodical flushing of inmemory blocks to files, so they aren't lost on unclean shutdown.
- Periodical syncing of metadata for persisted queues, so the metadata remains in sync with the persisted data.
- Automatic adjusting of too big chunk size when opening the queue. The chunk size may be bigger than the writer offset after unclean shutdown.
- Skipping of broken chunk file if it cannot be read.
- Fsyncing finalized chunk files.

Started from 1.17 k8s version endpointslices is beta,
it allows to query k8s api for endpoints more efficient.
It presents at scrape_config.yaml as separate role for kubernetes_sd_config.

Previously targets with big number of metrics and/or labels could generated too big buffers,

This resulted in memory waste.

Now big buffers are used only for targets with big number of metrics / labels,
while small buffers are used for targets with small number of metrics / labels.

2) All the goroutines return from Storage.AddRows.
3) The goroutine from step 1 blocks on searchTSIDsCond.Wait() inside the loop body.

The goroutine remains blocked until the next call to Storage.AddRows, which calls searchTSIDsCond.Signal().

b0131c79b6 lib/storage: improve search speed for time series matching Graphite whildcards such as foo.*.bar.baz
Add index for reverse Graphite-like metric names with dots. Use this index during search for filters
like `__name__=~"foo\\.[^.]*\\.bar\\.baz"` which end with non-empty suffix with dots, i.e. `.bar.baz` in this case.

This change may "hide" historical time series during queries. The workaround is to add `[.]*` to the end of regexp label filter,
i.e. "foo\\.[^.]*\\.bar\\.baz" should be substituted with "foo\\.[^.]*\\.bar\\.baz[.]*".

with the previous protocol. So it is required that both vminsert and vmstorage nodes are updated.

bf1869d33d lib/promscrape: allow overriding external_labels as Prometheus does
Prometheus docs at https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config say:

> In communication with external systems, they are always applied only
> when a time series does not have a given label yet and are ignored otherwise.

Though this may result in consistency chaos when scrape targets override `external_labels`,
let's stick with Prometheus behavior for the sake of backwards compatibility.

There is last resort in vmagent with `-remoteWrite.label`, which consistently
sets the configured labels to all the metrics before sending them to remote storage.

409c939621 lib/backup: remove flock.lock file in empty dirs
This fixes an issue when VictoriaMetrics doesn't see the restored data after the following operations:

1. Stop VictoriaMetrics.
2. Delete `<-storageDataPath>` dir.
3. Start VictoriaMetrics, then stop it.
4. Restore data from backup with `vmrestore`.
5. Start VictoriaMetrics.

`vmrestore` didn't delete properly empty dirs in `<-storageDataPath>/indexdb` because of the remaining `flock.lock` files in these dirs.

6f61fd367a lib/storage: add BenchmarkHeadPostingForMatchers similar to the benchmark from Prometheus
See the corresponding benchmark in Prometheus - 23c0299d85/tsdb/head_bench_test.go (L52)

The benchmark allows performing apples-to-apples comparison of time series search
in Prometheus and VictoriaMetrics. The following article - https://www.robustperception.io/evaluating-performance-and-correctness -
contains incorrect numbers for VictoriaMetrics, since there wasn't this benchmark yet. Fix it.

Benchmarks can be repeated with the following commands from Prometheus and VictoriaMetrics source code roots:

- Prometheus: GOMAXPROCS=1 go test ./tsdb/ -run=111 -bench=BenchmarkHeadPostingForMatchers
- VictoriaMetrics: GOMAXPROCS=1 go test ./lib/storage/ -run=111 -bench=BenchmarkHeadPostingForMatchers

494ad0fdb3 lib/storage: remove inmemory index for recent hour, since it uses too much memory
Production workload shows that the index requires ~4Kb of RAM per active time series.
This is too much for high number of active time series, so let's delete this index.

Now the queries should fall back to the index for the current day instead of the index
for the recent hour. The query performance for the current day index should be good enough
given the 100M rows/sec scan speed per CPU core.

5f52eb7653 lib/fs: do not postpone directory removal on NFS error
Continue trying to remove NFS directory on temporary errors for up to a minute.

The previous async removal process breaks in the following case during VictoriaMetrics start

- VictoriaMetrics opens index, finds incomplete merge transactions and starts replaying them.
- The transaction instructs removing old directories for parts, which were already merged into bigger part.
- VictoriaMetrics removes these directories, but their removal is delayed due to NFS errors.
- VictoriaMetrics scans partition directory after all the incomplete merge transactions are finished
  and finds directories, which should be removed, but weren't still removed due to NFS errors.
- VictoriaMetrics panics when it finds unexpected empty directory.

The origin of the error has been detected and documented in the code,

so it could be monitored and alerted on high error rates.

Export also the counter for processed index blocks with metricIDs - `vm_index_blocks_with_metric_ids_processed_total`,
so its' rate could be compared to `rate(vm_index_blocks_with_metric_ids_incorrect_order_total)`.

So panic on the first error when trying to remove directory in order
to simplify recover process.
