* lib/storage: creates parts.json on start-up if it not exists.
It fixes migrations from versions below v1.90.0.
Previously parts.json was created only after successful merge.
But if merge was interruped for some reason (OOM or shutdown), parts.json wasn't created and partitions left after interruped merge weren't properly deleted.
Since VM cannot check if it must be removed or not.

- Clarify the scope of the fix at docs/CHANGELOG.md
- Handle the case when -search.maxSamplesPerSeries limit is exceeded
in the same way as the -search.maxSamplesPerQuery limit.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4472
Properly return the error to user when `-search.maxSamplesPerQuery` limit is exceeded.
Before, user could have received a partial response instead.

This is a followup for https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4418 to also handle "connection reset by peer" errors in connection handling logic.
This error can be triggered just the same as described in original PR: when query was closed on vmselect side and connection has been interrupted.

This error may be wrapped in another error, and should normally be tested using
`errors.Is(err, net.ErrClosed)`.

app/vmagent/remotewrite: fix vmagent panic on shutdown
Currently, when vmagent is stopping it first flushes pending series in remote write context and proceeds to stop streaming aggregation. This leads to streaming aggregation being unable to write results into pending timeseries (since it is already nil) and panic.
This can lead to losing some aggregation results being lost almost silently.
The fix is reordering flow to first stop streaming aggregation and flush all pending time series after that.

The "broken pipe" error is emitted when the connection has been interrupted abruptly.
It could happen due to unexpected network glitch or because connection was
interrupted by remote client. In both cases, remote client will notice
connection breach and handle it on its own. No need in logging this error
on both: server and client side.
This change should reduce the amount of log noise on vmstorage side. In the same time,
it is not expected to lose any information, since important logs should be still
emitted by the vmselect.
To conduct an experiment for testing this change see the following instructions:
1. Setup vmcluster with at least 2 storage nodes, 1 vminsert and 1 vmselect
2. Run vmselect with complexity limit checked on the client side: `-search.maxSamplesPerQuery=1`
3. Ingest some data and query it back: `count({__name__!=""})`
4. Observe the logs on vmselect and vmstorage side
Before the change, vmselect will log message about complexity limits exceeded. When this happens,
vmselect closes network connections to vmstorage nodes signalizing that it doesn't expect any data back.
Both vmstorage processes will try to push data to the connection and will fail with "broken pipe" error,
means that vmselect closed the connection.
After the change, vmstorages should remain silent. And vmselect will continue emittin the error message
about complexity limits exceeded.
