app/vmalert: rm unnecessary err check
The error check was needed before a84491324d
It was kept by mistake and makes no sense to have rn.

app/vmalert: switch from table-driven tests to f-tests
This makes test code more clear and reduces the number of code lines by 500.
This also simplifies debugging tests. See https://itnext.io/f-tests-as-a-replacement-for-table-driven-tests-in-go-8814a8b19e9e

While at it, consistently use t.Fatal* instead of t.Error* across tests, since t.Error*
requires more boilerplate code, which can result in additional bugs inside tests.
While t.Error* allows writing logging errors for the same, this doesn't simplify fixing
broken tests most of the time.

This is a follow-up for a9525da8a4

all: consistently use 'any' instead of 'interface{}'
'any' type is supported starting from Go1.18. Let's consistently use it
instead of 'interface{}' type across the code base, since `any` is easier to read than 'interface{}'.

app/vmalert/rule: reduce number of allocations for getStaleSeries fn (#6269)

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
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

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`.
