lib/promscrape/discovery/kubernetes: log a warning if role: endpoints discovers more than 1000 targets per a single endpoint
In this case `role: endpointslice` must be used instead.

vmalert: remove extra / from path in WEB interface (#1717)
The extra `/` may cause issues when additional path prefixes
are configured. Also, removing it makes it consistent
with the rest of declarations.

vmctl influx convert bool to number (#1714)
vmctl: properly convert influx bools into integer representation

When using vmctl influx, the import would fail importing boolean fields
with:

```
failed to convert value "some".0 to float64: unexpected value type true
```

This converts `true` to `1` and `false` to `0`.

Fixes #1709

app/vmselect/promql: randomize the static selection of time series returned from limitk()
Sort series by a hash calculated from the series labels. This should guarantee "random" selection of the returned time series.
Previously the selection could be biased, since time series were sorted alphabetically by label names and label values.

lib/promscrape: always initialize http client for stream parsing mode
Stream parsing mode can be automatically enabled when scraping targets with big response bodies
exceeding the -promscrape.minResponseSizeForStreamParse , so it must be always initialized.

lib/promscrape: store the full response in stream parsing mode in scrapeWork.lastScrape byte slice
This allows sending staleness marks and properly calculate scrape_series_added metric in stream parsing mode
at the cost of the increased memory usage, since now the potentially big response is kept
in the lastScrape byte slice per each scrapeWork.

In practice the memory usage increase shouldn't be big, since the response size
is usually much smaller than the parsed metrics from this response after the relabeling,
which usually adds a big pile of target-specific labels per each metric.

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`.
