app/vmselect/promql: substitute rollupFuncsCannotAdjustWindow with rollupFuncsCanAdjustWindow
The list of functions, which can adjust lookbehind window is more limited than the rest of functions,
so it is better from maintainability and readability PoV using the allowlist instead of blocklist.

app/vmselect/promql: return back the behaviour for deriv() function when the lookbehind window doesnt contain enough points
It is expected that the `deriv(m[d])` returns non-empty value if the lookbehind window `d`
contains less than 2 samples in the same way as `rate()` does.

This is a follow-up after 3e084be06b .

app/vmselect: make predict_linear and deriv compatible with Prometheus (#1681)
Previously, `predict_linear` returned slightly different results comparing
to Prometheus. The change makes linear regression algorithm compatible
with Prometheus.

`deriv` was excluded from the list of functions which can adjust the time
window for the same reasons.

app/vmselect: quantile func compatiblity with Prometheus (#1646)
* app/vmselect: `quantile` func compatiblity with Prometheus

The `quantile` func was previously calculated by https://github.com/valyala/histogram
package. The result of such calculation was always the closest real value to
requested quantile. While in Prometheus implementation interpolation is used.
Such difference may result into discrepancy in output between Prometheus and
VictoriaMetrics.

This commit adds a Prometheus-like `quantile` function. It also used by other
functions which depend on it, such as `quantiles`, `quantile_over_time`, `median` etc.

* app/vmselect: `quantile` review fixes

* quantile functions were split into multiple to provide
different API for already sorted data;
* float64sPool is used for reducing allocations. Items in pool may have
different sizes, but defining a new pool was complicates due to name collisions;

The commit contains the following changes:

- Show vmui when requesting /graph page in order to be compatible with Prometheus datasource in Grafana.
- Properly encode query args at vmui url.
- Set the number of points on the graph to the number of horizontal pixels divided by 2. Previously it was hardcoded to 30.
- Do not save server url to persistent storage at browser, since it should be always obtained from the url.
- Run `make vmui-update` for updating vmui embedded into VictoriaMetrics.

vmselect: update vm_request_duration_seconds value when request fails (#1537)
Before, metric `vm_request_duration_seconds` was update only on successful

request may be not accounted in the metric and won't be visible on dashboards.
Using `defer` statement to update the metric after query arguments validation

vmalert: expose new metrics for tracking number of produced samples during last evaluation (#1518)
* vmalert: expose new metrics for tracking number of produced samples during last evaluation

Two new metrics were added to track the number of samples produced during the last evaluation:
* vmalert_recording_rules_last_evaluation_samples
* vmalert_alerting_rules_last_evaluation_samples

The gauge type is used to remain consistent with Prometheus metric
`prometheus_rule_group_last_evaluation_samples` which is on the group level.
However, the counter type was considered as well.

Two metrics instead of one are used to make it easier to separate recording and
alerting rules. It is likely, number of samples produced by recording rules is
more important so people will refer to it more frequently.

The expected usage of the new metric is the following:
```
   - alert: RecordingRuleReturnsEmptyResults
        expr: sum(vmalert_recording_rules_last_evaluation_samples) by(recording) < 1
        annotations:
          summary: Recording rule {{$labels.recording}} returns empty results.
            Please verify expression correctness.
```

vmalert: support rules backfilling (aka replay) (#1358)
* 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.

vmalert: use stringified label keys for duplicates map in recroding rules (#1301)
duplicates map helps to determine wheter extra labels has overriden
labels which make time series unique. It was using a sorted hashed
labels sequence as a key. But hashing algorithm could have collisions,
so it is more convenient to not use hashing at all.

Log message for recording rules duplicates was improved as well.

vmalert: add flag to control behaviour on startup for state restore errors (#1265)
Alerting rules now can return specific error type ErrStateRestore to indicate
whether restore state procedure failed. Such errors were returned and logged
before as well. But now user can specify whether to just log these errors
(remoteRead.ignoreRestoreErrors=true) or to stop the process
(remoteRead.ignoreRestoreErrors=false). The latter is important when VM isn't
ready yet to serve queries from vmalert and it needs to wait.

Vmalert: adjust time param for datasource queries according to evaluationInterval (#1257)
* Simplify arguments list for fn `queryDataSource` to improve readbility

* vmalert: adjust `time` param according to rule evaluation interval

With this change, vmalert will start to use rule's evaluation interval
for truncating the `time` param. This is mostly needed to produce consistent
time series with timestamps unaffected by vmalert start time. Now, timestamp
becomes predictable.
Additionally, adjustment is similar to what Grafana does for plotting range graphs.
Hence, recording rule series and recording rule expression plotted in grafana
suppose to become similar in most of cases.

vmalert: keep the returned timestamp when persisting recording rule (#1245)
Previously, vmalert used `lastExecTime` timestamp when writing recording rules
to the remote storage. This may be incorrect, if vmalert uses `datasource.lookback` flag,
which means rule's expression will be executed at some moment in the past.
To avoid such situations, vmalert now will use returned timestamp instead of `lastExecTime`.

docs: update docs ordering and formatting (#1192)
The major change is adding `sort` directive to docs. For those docs which are copied
from internal packages `sort` is added via makefile command. For the rest it is added
manually since they're updated manually as well.

The rest of changes is connected with markdown formatting. For example, changing headers
in some files (`##` => `#`) makes navigation on .github.io to look better. This especially
useful for `changelog` docs.

Table of contents for `vmctl` is dropped, since we already have it autogenerated on .github.io.

No link changes expected. The corresponding PR to `cluster` branch will be made in follow-up PR.

vmalert-989: return non-empty result in template func query stub to pass validation (#1002)
On templates validation stage vmalert does not acutally send queries, so for complex
chained expression validation may fail. To avoid this, we add a blank sample in response
so validation can pass successfully. Later, during the rule execution, stub will be replaced
with real `query` function.

vmalert: add function "query", "first" and "value" to alert templates functions (#960)
The commit adds a support for template function `query`,
`first` and `value`. The function `query` executes
a MetricsQL query for active alerts. In vmalert we
update templates on every evaluation for active alerts
to keep them up to date. With `query` func it may become
a perf issue since it will fire a query on every execution.
We should keep it in mind for now.

vmalert: explicitly set extra labels to alert entities (#886)
The previous implementation treated extra labels (global and rule labels) as
separate label set to returned time series labels. Hence, time series always contained
only original labels and alert ID was generated from sorted labels key-values.
Extra labels didn't affect the generated ID and were applied on the following actions:
- templating for Summary and Annotations;
- persisting state via remote write;
- restoring state via remote read.

Such behaviour caused difficulties on restore procedure because extra labels had to be dropped
before checking the alert ID, but that not always worked. Consider the case when expression
returns the following time series `up{job="foo"}` and rule has extra label `job=bar`.
This would mean that restored alert ID will be always different to the real time series because
of collision.

To solve the situation extra labels are now always applied beforehand and `vmalert` doesn't
store original labels anymore. However, this could result into a new error situation.
Consider the case when expression returns two time series `up{job="foo"}` and `up{job="baz"}`,
while rule has extra label `job=bar`. In such case, applying extra labels will result into
two identical time series and `vmalert` will return error:
 `result contains metrics with the same labelset after applying rule labels`
