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.

new feature: debug relabeling (#1344) 
* new feature: relabel logging

Use scrape_configs[x].relabel_debug = true to log metric names inkl.
labels before and after relabeling. After relabeling related metrics
get dropped, i.e. not submitted to servers.

* vminsert wants relabel logging, too.

vmalert: automatically reload configuration on file change (#1326) 
New flag `-rule.configCheckInterval` defines how often `vmalert` will re-read
config file. If it detects any changes, the config will be reloaded.
This behaviour is turned off by default.

vmalert: support extra_filter_labels setting per-group (#1319) 
The new setting `extra_filter_labels` may be assigned to group.
If it is, then all rules within a group will automatically filter
for configured labels. The feature is well-described here
https://docs.victoriametrics.com#prometheus-querying-api-enhancements

New setting is compatible only with VM datasource.

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 support for round_digits param in datasource package (#1278) 
Starting from v1.56.0 VM supports `round_digits` which allows to limit
the number of digits after the decimal point in response value. The feature
can be used to reduce entropy of produced by recording rules values
and significantly improve the compression. See more details in link below.

vmalert: fix error when rule didn't start if restore failed (#1279)

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`

82973f8ae7 Revert "lib/storage: remove unused fetchData arg from BlockRef.MustReadBlock" 
This reverts commit bab6a15ae0.

Reason for revert: the `fetchData` arg is used in cluster branch.
Leaving this arg in master branch makes smaller the diff with cluster branch.

vmalert: update groups on config reload only if changes detected (#759) 
On config reload event `vmalert` reloads configuration for every group. While
it works for simple configurations, the more complex and heavy installations may
suffer from frequent config reloads.
The change introduces the `checksum` field for every group and is set to md5 hash
of yaml configuration. The checksum will change if on any change to group
definition like rules order or annotation change. Comparing the `checksum` field
on config reload event helps to detect if group should be updated.
The groups update is now done concurrently, so reload duration will be limited by
the slowest group now.

Partially solves #691 by improving config reload speed.
