app/vmalert: follow-up after c9375cac5e
c9375cac5e

Descriptions were updated in attempt to make it more clear for readers,
re-phrasing and linking missing docs.

`eval_delay` was added to tests to verify it can be unmarshalled.

`eval_delay` is now applied before timestamp alignment to make it more predictable.
Before, if delay < interval the timestamp won't be aligned.

`eval_delay` and `eval_offset` was added to API output.

`PreviouslySentSeriesToRW` converted to private `previouslySentSeriesToRW`.

1. address https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4959. skip job with wrong syntax in `scrape_configs` with error logs instead of exiting;
2. show error messages on vmagent /targets ui if there are wrong auth configs in `scrape_configs`, previously will print error logs and do scrape without auth header;
3. don't send requests if there are wrong auth configs in:
    1. vmagent remoteWrite;
    2. vmalert datasource/remoteRead/remoteWrite/notifier.

lib/license: cleanups and prettifications for log messages and docs related to licensing
- Make more clear the docs at docs/enterprise.md, so readers could figure out faster
  on how to obtain enterprise key and how to pass it to VictoriaMetrics Enterprise components.

- Fix examples at docs/enterprise.md, which were referring to non-existing `-license-file` command-line flag.
  The `-licenseFile` command-line flag must be used instead.

- Improve the description of `-license*` command-line flags, so users could understand
  faster how to use them.

- Improve the warning message, which is emitted when the deprecated -eula command-line flag is passed,
  so the user could figure out how to switch faster to -license* command-line flags.

- Disallow running VictoriaMetrics components with both -license and -licenseFile command-line flags.

- Disallow running VictoriaMetrics components when -licensFile points to an empty file.

- Consistently use the phrase "This flag is available only in Enterprise binaries" across
  all the enterprise-specific command-line flags.

- Remove unneeded level of indirection for `noLicenseMessage` and `expiredMessage` string contants
  in order to improve code readability and maintainability.

- Remove unneded `return` statements after `logger.Fatalf()` calls, since these calls exit the app and never return.

- Make sure that the info log message about successful license verification is emitted
  when the license is verified successfully. Previously the error message could be logged
  when the license payload is invalid or if it misses some required features.

vmalert: add evalAlignment for rule group and fix evalutaion timstamp (#5066)
* vmalert: add `query_time_alignment` for rule group

1. add `eval_alignment` attribute for group which by default is true. So group rule query stamp will be aligned with interval and propagated to ALERT metrics and the messages for alertmanager;
2. deprecate `datasource.queryTimeAlignment` flag.

app/vmalert: hide sensetive info in the vmalert (#5059)
Strip sensitive information such as auth headers or passwords from datasource, remote-read, 
remote-write or notifier URLs in log messages or UI. This behavior is by default and is controlled via 
`-datasource.showURL`, `-remoteRead.showURL`, `remoteWrite.showURL` or `-notifier.showURL` cmd-line flags.

vmalert: set default value for datasource.queryStep to 5m (#3149)
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: 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.

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`.

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
