lib/promauth: follow-up for e16d3f5639
- Make sure that invalid/missing TLS CA file or TLS client certificate files at vmagent startup
  don't prevent from processing the corresponding scrape targets after the file becomes correct,
  without the need to restart vmagent.
  Previously scrape targets with invalid TLS CA file or TLS client certificate files
  were permanently dropped after the first attempt to initialize them, and they didn't
  appear until the next vmagent reload or the next change in other places of the loaded scrape configs.

- Make sure that TLS CA is properly re-loaded from file after it changes without the need to restart vmagent.
  Previously the old TLS CA was used until vmagent restart.

- Properly handle errors during http request creation for the second attempt to send data to remote system
  at vmagent and vmalert. Previously failed request creation could result in nil pointer dereferencing,
  since the returned request is nil on error.

- Add more context to the logged error during AWS sigv4 request signing before sending the data to -remoteWrite.url at vmagent.
  Previously it could miss details on the source of the request.

- Do not create a new HTTP client per second when generating OAuth2 token needed to put in Authorization header
  of every http request issued by vmagent during service discovery or target scraping.
  Re-use the HTTP client instead until the corresponding scrape config changes.

- Cache error at lib/promauth.Config.GetAuthHeader() in the same way as the auth header is cached,
  e.g. the error is cached for a second now. This should reduce load on CPU and OAuth2 server
  when auth header cannot be obtained because of temporary error.

- Share tls.Config.GetClientCertificate function among multiple scrape targets with the same tls_config.
  Cache the loaded certificate and the error for one second. This should significantly reduce CPU load
  when scraping big number of targets with the same tls_config.

- Allow loading TLS certificates from HTTP and HTTPs urls by specifying these urls at `tls_config->cert_file` and `tls_config->key_file`.

- Improve test coverage at lib/promauth

- Skip unreachable or invalid files specified at `scrape_config_files` during vmagent startup, since these files may become valid later.
  Previously vmagent was exitting in this case.

docs: use https://github.com/VictoriaMetrics/VictoriaMetrics/releases/latest instead of https://github.com/VictoriaMetrics/VictoriaMetrics/releases link where needed
The https://github.com/VictoriaMetrics/VictoriaMetrics/releases link may show non-latest
releases at the top, such as LTS releases or VictoriaLogs releases.
So it is better to use https://github.com/VictoriaMetrics/VictoriaMetrics/releases/latest link,
which always redirect to the latest available release of VictoriaMetrics.

fix inconsistent behaviors with prometheus when scraping (#5153)
* fix inconsistent behaviors with prometheus when scraping

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.

* add changelogs

* address review comments

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`.

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 `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.

Previosly, request retry to datasource re-used existing HTTP request.
But if request object was already partially processed (body was read),
then retry will be unsuccessful.

vmalert: update retry policy for pushing data to -remoteWrite.url (#4504)
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.

* vmalert: fix nil map assignment

The storage instance with nil map params was created for remote-read purposes.
And before change 7a9ae9de0d this map was ignored in ApplyParams.
Now, it started to be used and vmalert panics in runtime.

The fix properly inits map for at `NewVMStorage` and verifies it is not nil
on assignment in `ApplyParams`.

groups by: errors only or noMatch only.

The filtering supposed to help navigating big numbers of groups/rules.
Filtering is reflected in URL, so can be shared as a link.

in response - use amount of samples as number of series.

app/vmalert: detect alerting rules which don't match any series at all (#4198)
app/vmalert: detect alerting rules which don't match any series at all

vmalert starts to understand /query responses which contain object:
```
"stats":{"seriesFetched": "42"}
```
If object is present, vmalert parses it and populates a new field
`SeriesFetched`. This field is then used to populate the new metric
`vmalert_alerting_rules_last_evaluation_series_fetched` and to
display warnings in the vmalert's UI.

If response doesn't contain the new object (Prometheus or
VictoriaMetrics earlier than v1.90), then `SeriesFetched=nil`.
In this case, UI will contain no additional warnings.
And `vmalert_alerting_rules_last_evaluation_series_fetched` will
be set to `-1`. Negative value of the metric will help to compile
correct alerting rule in follow-up.

Thanks for the initial implementation to @Haleygo

vmalert: support logs suppressing during config reloads (#3973)
* vmalert: support logs suppressing during config reloads

The change is mostly required for ENT version of vmalert,
since it supports object-storage for config files.
Reading data from object storage could be time-consuming,
so vmalert emits logs to track the progress.

However, these logs are mostly needed on start or on
manual config reload. Printing these logs each time
`rule.configCheckInterval` is triggered would too verbose.
So the change allows to control logs emitting during
config reloads.

Now, logs are emitted during start up or when SIGHUP is receieved.
For periodicall config checks logs emitted by config pkg are suppressed.
