app/vmalert: make TestGroupStart more reliable (#6130)
There was a sleep statement in the test, waiting for Group
to perform a couple of evaluation. But looks like
it worked unreliable for some CI tests like the one below
https://github.com/VictoriaMetrics/VictoriaMetrics/actions/runs/8718213844/job/23915007958?pr=6115

This commit changes the sleep statement on a function that
waits for a specific number of evaluations. It should make this
test faster in general case, and more reliable for slow environemnts.

vmalert: fix sending alert messages (#6028)
* vmalert: fix sending alert messages
1. fix `endsAt` field in messages that send to alertmanager, previously rule with small interval could never be triggered;
2. fix behavior of `-rule.resendDelay`, before it could prevent sending firing message when rule state is volatile.

* docs: update changelog notes

vmalert: set ActiveAt to evaluation timestamp in newAlert fn (#5657)
The change fixes flaky test `TestAlertingRule_Exec` which has dependency on the actual timestamps,
which resulted into inaccurate test states:

app/vmalert: autogenerate ALERTS_FOR_STATE time series for alerting rules with for: 0 (#5680)
* app/vmalert: autogenerate `ALERTS_FOR_STATE` time series for alerting rules with `for: 0`

 Previously, `ALERTS_FOR_STATE` was generated only for alerts with `for > 0`.
 This behavior differs from Prometheus behavior - it generates ALERTS_FOR_STATE
 time series for alerting rules with `for: 0` as well. Such time series can
 be useful for tracking the moment when alerting rule became active.

app/vmalert: update remote-write process (#5284)
* app/vmalert: update remote-write process

* automatically retry remote-write requests on closed connections. The change should reduce the amount of logs produced in environments with short-living connections or environments without support of keep-alive on network balancers.
* increment `vmalert_remotewrite_errors_total` metric if all retries to send remote-write request failed. Before, this metric was incremented only if remote-write client's buffer is overloaded.
* increment `vmalert_remotewrite_dropped_rows_total` amd `vmalert_remotewrite_dropped_bytes_total` metrics if remote-write client's buffer is overloaded. Before, these metrics were incremented only after unsuccessful HTTP calls.

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`.
