support `Strict-Transport-Security`, `Content-Security-Policy` and `X-Frame-Options`
HTTP headers in all VictoriaMetrics components.
The values for headers can be specified by users via the following flags:
`-http.header.hsts`, `-http.header.csp` and `-http.header.frameOptions`.

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`.

- 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 `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.
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5049
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.
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5044
Adds `eval_offset` attribute for Groups.
If specified, Group will be evaluated at the exact time offset on the range of [0...evaluationInterval].
The setting might be useful for cron-like rules which must be evaluated at specific moments of time.

Value of `-dedup.minScrapeInterval` comand-line flag must be higher than `evaluation_interval` in order to make sure that only one sample on each evaluation will be left after deduplication.
Moreover, value of `-dedup.minScrapeInterval` must be a multiple of vmalert's `evaluation_interval` in order to make sure that samples will be aligned between deduplication window periods.

The important change is to highlight that restore procedure happens
only once and only for already loaded rules. Config hot-reload
doesn't trigger the restore procedure.

vmalert: allow disabling of `step` param attached to instant queries
This might be useful for using vmalert with datasources that to not support this param,
unlike VictoriaMetrics.

By default, vmalert will make multiple retry attempts with exponential delay.
The total time spent during retry attempts shouldn't exceed `-remoteWrite.retryMaxTime` (default is 30s).
When retry time is exceeded vmalert drops the data dedicated for `-remoteWrite.url`.
Before, vmalert dropped data after 5 retry attempts with 1s delay between attempts (not configurable).
See `-remoteWrite.retryMinInterval` and `-remoteWrite.retryMaxTime` cmd-line flags.
