lib/storage: subsitute searchTSIDs functions with more lightweight searchMetricIDs function
The searchTSIDs function was searching for metricIDs matching the the given tag filters
and then was locating the corresponding TSID entries for the found metricIDs.

The TSID entries aren't needed when searching for time series names (aka MetricName),
so this commit removes the uneeded TSID search from the implementation of /api/v1/series API.
This improves perfromance of /api/v1/series calls.

This commit also improves performance a bit for /api/v1/query and /api/v1/query_range calls,
since now these calls cache small metricIDs instead of big TSID entries
in the indexdb/tagFilters cache (now this cache is named indexdb/tagFiltersToMetricIDs)
without the need to compress the saved entries in order to save cache space.

This commit also removes concurrency limiter during searching for matching time series,
which was introduced in 8f16388428, since the concurrency
for all the read queries is already limited with -search.maxConcurrentRequests command-line flag.

lib/promscrape: allow specifying full target url in __address__ label
Previously the `__address__` label could contain only `host:port` part of the target url,
while the scheme and metrics path were obtained from `__scheme__` and `__metrics_path__`
labels. Now it is possible to set the full url in `__address__` label.

This makes valid the following scrape config, which is frequently used by novice users:

scrape_configs:
- job_name: foo
  static_configs:
  - targets:
    - http://host1/metrics1
    - https://host2/metrics2

app/vmselect/promql: remove empty series before applying aggregate function
Previously empty series (e.g. series with all NaN samples) were passed to aggregate functions.
Such series must be ingored by all the aggregate functions.
So it is better from consistency PoV filtering out empty series before applying aggregate functions.

app/vmselect: ignore empty series for limit_offset (#3178)
* app/vmselect: ignore empty series for `limit_offset`

VictoriaMetrics doesn't return empty series (with all NaN values) to
the user. But such series are filtered after transform functions.
It means `limit_offset` will account for empty series as well.

For example, let's consider following data set:
```
time series:
foo{label="1"} NaN, NaN, NaN, NaN // empty series
foo{label="2"} 1, 2, 3, 4
foo{label="3"} 4, 3, 2, 1
```

When user requests all series for metric `foo` the empty series
will be filtered out:
```
/query=foo:
foo{label="v2"} 1, 2, 3, 4
foo{label="v3"} 4, 3, 2, 1
```

But `limit_offset(1, 1, foo)` is applied to original series, not filtered yet.
So it will return `foo{label="v2"}` (skips the first in list)
```
/query=limit_offset(1, 1, foo):
foo{label="v2"} 1, 2, 3, 4
```

Expected result would be to apply `limit_offset` to already filtered list,
so in result we receive `foo{label="v3"}`:
```
/query=limit_offset(1, 1, foo):
foo{label="v3"} 4, 3, 2, 1
```

The change does exactly that - filters empty series before applying `limit_offset`.

vmalert: set default value for datasource.queryStep to 5m (#3149)
Change default value for command-line flag `datasource.queryStep` from `0s` to `5m`.
Param `step` is added by vmalert to every rule evaluation request sent to datasource.
Before this change, `step` was equal to group's evaluation interval by default.
Param `step` for instant queries defines how far VM can look back for the last written data point.
The change supposed to improve reliability of the rules evaluation when evaluation interval
is lower than scraping interval.

vmalert: always re-evaluate Annotations (#3119)
* vmalert: always re-evaluate Annotations

Previously, Annotations were evaluated only:
1. On alert creating.
2. On alert's value change.

This is premature optimization. It was assumed that since annotations
could contain only text with alert's labels or value - there is no need
in spending resources to re-compile Annotations.

Later, template function `query` was added, which can execute
arbitrary queries and return different results on every evaluation.
So if it was used in annotations, it would be executed only on init
or value change.

Another case when optimization caused an issue - annotations hot reload.
In this case, annotations of the active alert won't change even if Rule's
annotations were changed.

This fix enables Annotations re-evaluation on each iteration to resolve
issues above. It would have some impact on performance, but it is unlikely
it will be noticeable.

This change modifies the format for data exported via /api/v1/export/native -
now this data contains MaxTimestamp and PrecisionBits fields from blockHeader.

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: improve scalability of blocks processing on systems with multiple CPU cores
Previously a single syncwg.WaitGroup was used for tracking the lifetime of processBlock callbacks
across all the per-vmstorage goroutines. This could be slow on systems with many CPU cores
because of inter-CPU synchronization overhead.

Use a separate per-vmstorage sync.WaitGroup instead in order to reduce inter-CPU synchronization overhead.
This should imrpove performance for heavy queries over big number of blocks on multi-CPU systems.

lib/storage: prevent excessive loops when storage is in RO (#2962)
* lib/storage: prevent excessive loops when storage is in RO

Returning nil error when storage is in RO mode results
into excessive loops and function calls which could
result into CPU exhaustion. Returning an err instead
will trigger delays in the for loop and save some resources.

vmalert: remove notions of vmalert being compatible with VM only (#2954)
vmalert can be successfully used with datasources
compatible with Prometheus HTTP API. So we remove comments or
notes in Readme which are saying opposite.

Makefile: remove redundant -mod=vendor option when running Go tools
The `-mod=vendor` is automatically set when there is a `vendor` directory
starting from Go1.14 - see https://go.dev/doc/go1.14#go-command

Since the minimum supported Go version for VictoriaMetrics is Go1.17,
then the `-mod=vendor` option is no longer needed.
