all: use os.{Read|Write}File instead of ioutil.{Read|Write}File
The ioutil.{Read|Write}File is deprecated since Go1.16 -
see https://tip.golang.org/doc/go1.16#ioutil

VictoriaMetrics needs at least Go1.18, so it is safe to remove ioutil usage
from source code.

This is a follow-up for 02ca2342ab

lib/storage: bump max merge concurrency for small parts to 15 (#2997)
* lib/storage: bump max merge concurrency for small parts to 15

The change is based on the feedback from users on github.
Thier examples show, that limit of 8 sometimes become a
bottleneck. Users report that without limit concurrency
can climb up to 15-20 merges at once.

vmalert: set alert's source link to UI instead of JSON source (#2986)
We switch default alert's source link to redirect user
to vmalert's UI instead of previous JSON object. While it breaks
compatibility, it also supposed to improve user's experience.
The old behavior can be achieved by updating `-external.alert.source`
command-line flag.

app/vmselect/netstorage: fix a bug introduced in 1a254ea20c
The bug results in `duplicate output time series` error
because the same time series is added two times into the orderedMetricNames list
inside the tmpBlocksFileWrapper.Finalize().

While at it, properly release all the tmpBlocksFile structs on tbf.Finalize() error.
Previously only the remaining tbf entries were released. This could result in resource leak.

lib/promscrape: automatically generate additional per-target labels for targets with non-zero series limit
The following metrics are generated:

- scrape_series_limit
- scrape_series_current
- scrape_series_limit_samples_dropped

These metrics simplify alerting on targets, which expose too many time series

See https://docs.victoriametrics.com/vmagent.html#automatically-generated-metrics
and https://docs.victoriametrics.com/vmagent.html#cardinality-limiter for more details

* Explicitly store a pointer to UserReadableError in the error interface.
  Previously Go automatically converted the value to a pointer before storing in the error interface.

* Add Unwrap() method to UserReadableError, so it can be used transparently with the other code,
  which calls errors.Is() and errors.As().

* Document the change in docs/CHANGELOG.md

vmselect: introduce UserReadableError type of error (#2894)
When read query fails, VM returns rich error message with
all the details. While these details might be useful
for debugging specific cases, they're usually too verbose
for users.
Introducing a new error type `UserReadableError` is supposed
to allow to return to user only the most important parts
of the error trace. This supposed to improve error readability
in web interfaces such as VMUI or Grafana.

The full error trace is still logged with the full context
and can be found in vmselect logs.
