vmalert: mark some url flags as sensitive (#2965)
Other components, such as `vmagent`, mark these flags as sensitive and
hide them from the `/metrics` endpoint by default. This commit adds
similar handling to the `vmalert` component, hiding them by default, to
prevent logging of secrets inappropriately.

Showing of these values is controlled by an additional flag.

vmalert: add flag for disabling long-lived connections (keepalive) (#2395)
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.

Vmalert compliance improvements (#2320)
* vmalert: add support for `sortByLabel` template function

* vmalert: update API according to Prometheus conformance program

The changes to the API, field names and URL path has been made
according to the Prometheus specification for `alert_generator`
https://github.com/prometheus/compliance/blob/main/alert_generator/specification.md

* vmalert: fix the timestamp of the evaluated rules

The timestamp used for alert's `EndsAt` was calculated
before sending the notification. While the correct way
is to use the timestamp taken right before rules evaluation.

* vmalert: add `-datasource.queryTimeAlignment` flag

The flag is supposed to provide ability to disable `time`
param alignment when executing rules. By default, this flag
is enabled, so it remains backward compatible.

The flag was introduced to achieve better compatibility
with Prometheus behaviour according to https://github.com/prometheus/compliance/blob/main/alert_generator/specification.md

vmalert: introduce additional HTTP URL params per-group configuration (#1892)
* vmalert: introduce additional HTTP URL params per-group configuration

The new group field `params` allows to configure custom HTTP URL params
per each group. These params will be applied to every request before
executing rule's expression. Hot config reload is also supported.

Field `extra_filter_labels` was deprecated in favour of `params` field.
vmalert will print deprecation log message if config file contains
the deprecated field.

`params` fields are supported by both Prometheus and Graphite datasource types.

* vmalert: provide more examples for `params` field

Signed-off-by: hagen1778 <roman@victoriametrics.com>

* vmalert: set higher priority for `params` setting

If there would be a conflict between URL params set in `datasource.url` flag
and params in group definition the latter will have higher priority.

Adjust http.Transport.MaxIdleConns setting for vmauth/vmalert services (#1704)
* vmalert: adjust `http.Transport.MaxIdleConns` value accordingly to `http.Transport.MaxIdleConnsPerHost`

`http.Transport.MaxIdleConnsPerHost` setting is controlled by `datasource.maxIdleConnections` flag,
while `http.Transport.MaxIdleConns` is inherited from DefaultTransport and is equal to `100`.
The fix adjusts `http.Transport.MaxIdleConns` value if it is lower than `http.Transport.MaxIdleConnsPerHost`.

1cf4f5a715 Vmalert extra params (#1587)
* vmalert: allow extra GET params in datasource package

ExtraParams will be added as GET params to every HTTP request made by datasource.
The `roundDigits` param, for example, was substituted by corresponding extra param.

* vmalert: add nocache=1 param for replay process

The `nocache=1` param is VictoriaMetrics specific parameter which prevents it
from caching and boundaries aligning for queries. We set it to avoid cache
pollution in `replay` mode and also to avoid unnecessary time range boundaries
alignment.

* vmalert: mention nocache=1 in replay description

* vmalert: fix bug with unused param

a7f00101f5 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.
