* vmselect: introduce `search.skipSlowReplicas` cmd-line flag
vmselect has two logical conditions during request processing when
`-replicationFactor` cmd-line flag is set:
1. If at least `len(storageNodes) - replicationFactor` responded, it could skip
waiting for the rest of nodes to respond. This could lead to problems described
here https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1207.
2. Mark response as partial if less than `len(storageNodes) - replicationFactor` responded
without an error.
The P1 showed itself error-prone and became the main reason why
`-replicationFactor` wasn't recommended to use at vmselect level.
However, this optimization could be still very useful in situations
when there are slow and fast replicas in cluster.
But P2 remains viable and important conditionless.
Hiding P1 behind the feature-flag `search.skipSlowReplicas`
should make `-replicationFactor` flag usable again. And let users
choose whether they want P1 to be respected.

- 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.

The validation was needed for covering corner cases when storage is tested with data from 1970.
This resulted into unexpected search results, as year was parsed incorrectly from the given timestamp.

The change focuses on rectifying inconsistencies in the navigation behavior of the application
and eliminating issues encountered when manually altering the URL.
The key updates include:
- Refactoring of the routing mechanism to handle all possible routes and their states.
- Enhancement of the React Router usage to ensure a smoother navigation experience.
- Handling application state when the URL is manually changed.
expose `vmauth_user_request_duration_seconds`
and `vmauth_unauthorized_user_request_duration_seconds` summary metrics
for measuring requests latency per user.

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.

* 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.

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.

* 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`.
