lib/promscrape: properly add exported_ prefix to labels, which clash with target labels if honor_labels: true option isn't set.
The issue was in the `labels := dst[offset:]` line in the beginning of appendExtraLabels() function.
The `dst` may be re-allocated when adding extra labels to it. In this case the addition of `exported_`
prefix to labels inside `labels` slice become invisible in the returned `dst` labels.

While at it, properly handle some corner cases:

- Add additional `exported_` prefix to clashing metric labels with already existing `exported_` prefix.
- Store scraped metric names in `exported___name__` label if scrape target contains `__name__` label.

app/vmalert/templates: properly escape all the special chars in quotesEscape function
Previously the `quotesEscape` function was escaping only double quotes.
This wasn't enough, since the input string could contain other special chars,
which must be escaped when put inside JSON string. For example, carriage return and line feed chars (\n\r),
backslash char, etc. This led to the following issues, which were improperly fixed:

- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/890 - this issue
  was "fixed" by introducing the `crlfEscape` function, which led to unnecessary
  complications in user templates, while not fixing various corner cases
  such as backslash chars in the input string.
  See 1de15ad490

- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3139 - this issue
  was "fixed" by urlencoding the whole string passed to -external.alert.source
  command-line flag. This led to invalid urls, which couldn't be parsed by Grafana.
  See 00c838353d
  and 4bd0244599

This commit properly encodes the input string passed to `quotesEscape`, so it can be safely embedded inside JSON strings.

This commit deprecates crlfEscape template function and adds the following new template functions:

- strvalue and stripDomain - these functions are supported by Prometheus, so they were added
  for compatibility purposes.
- jsonEscape and htmlEscape for converting the input string to valid quoted JSON string
  and for html-escaping the input string, so it could be safely embedded as a plaintext
  into html.

This commit also documents all supported template functions at https://docs.victoriametrics.com/vmalert.html#template-functions
The deprecated crlfEscape function isn't documented on purpose, since its usefulness is negative in general case.

Revert "vmalert: escape query params if external alert source defined ()"
This reverts commit 00c838353d.

Reason for revert: it incorrectly fixes the issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3139 .
Now `-external.alert.source=explore?orgId=1&left=...` is converted to the following invalid url, which cannot be handled by Grafana:

https://grafana.example.com/explore%3ForgId%3D1%26left%3D...

The next commit will contain the correct fix of the issue - the `quotesEscape` function must
properly escape the string, so it could be embedded into JSON string. This function must
properly escape \n\r chars too. In this case the `crlfEscape` function becomes unnecessary.
Actually, the next commit makes the `crlfEscape` function deprecated.

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 ()
* 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 ()
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 ()
* 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.

lib/promscrape: optimize discoveryutils.SanitizeLabelName()
Cache sanitized label names and return them next time.
This reduces the number of allocations and speeds up the SanitizeLabelName()
function for common case when the number of unique label names is smaller than 100k

lib/promrelabel: optimize matching for commonly used regex patterns in if option
The following regex patterns are optimized:

- literal string match, e.g. "foo"
- prefix match, e.g. "foo.*" and "foo.+"
- substring match, e.g. ".*foo.*" and ".+foo.+"
- alternate values match, e.g. "foo|bar|baz"

app/vmstorage: expose vm_{hourly,daily}_series_limit_{max,current}_series metrics if -storage.max{Hourly,Daily}Series limits are set
These metrics allow alerting when the number of unique series approach the limit.
For example, the following query alerts when the number of series reaches 90% of the configured limit:

    vm_hourly_series_limit_current_series / vm_hourly_series_limit_max_series > 0.9

vmalert: set alert's source link to UI instead of JSON source ()
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.

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

- 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
