The default value of `-datasource.queryStep` has changed, so we update
the troubleshooting docs accordingly.

* Use vm_account_id and vm_project_id labels to be consistent with https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#multitenancy-via-labels
* Document the feature that vmalert now exposes vm_account_id and vm_project_id
labels if -clusterMode is set.
* Use literal strings instead of string constants for vm_account_id and vm_project_id.
This improves code readability.
Allow configuring authorization params per list of targets
in vmalert's notifier config for `static_configs`.

- Clarify the description for -datasource.queryStep command-line flag
- Consistently use a single dash in front of -datasource.queryStep command-line flag
- Update -help output at docs/vmalert.md
- Consistently use single dash in front of command-line flags instead of double dashes.
- Add a warning that too small -search.latencyOffset may lead to incomplete query results.
vmalert: add experimental feature of storing Rule's evaluation state
The new feature keeps last 20 state changes of each Rule
in memory. The state are available for view on the Rule's
view page. The page can be opened by clicking on `Details`
link next to Rule's name on the `/groups` page.
States change suppose to help in investigating cases when Rule
doesn't generate alerts or records.

* vmalert: add `debug` mode for alerting rules
Debug information includes alerts state changes and requests
sent to the datasource. Debug can be enabled only on rule's
level. It might be useful for debugging unexpected
behaviour of alerting rule.

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.

vmalert can be successfully used with datasources
compatible with Prometheus HTTP API. So we remove comments or
notes in Readme which are saying opposite.

* vmalert: deprecate alert's status link
Deprecate alert's status link `/api/v1/<groupID>/<alertID>/status` in favour of
`api/v1/alerts?group_id=<group_id>&alert_id=<alert_id>"`.
The change was needed for simplifying logic in vmselect for proxying vmalert's requests.
The old alert's status link will be still supported for a few versions but will be removed in the future.

vmalert: support `limit` param in groups definition
`limit` param limits number of time series samples produced by a single rule
during execution.
On reaching the limit rule will return an err.

For liquid text processor double braces `{{` `}}`
are special chars for templating.
Since we use them in some of our docs with different purpose,
we must escape them to avoid syntax errors from liquid.
For escaping curly braces we use bult-in plugin which helps
to enclose sections of text via `{% raw %}` and `{% endraw %}`.
This approach prevents liquid syntax errors and makes render correct.

The new flag `datasource.disableKeepAlive` allows disabling keepalive
connections. This may be useful if there are multiple datasource
replicas (e.g. vmselects) behind the HTTP balancer to avoid uneven
load spread because of long-lived connections.
