When at least one remote write has deduplication configured it cleans up
timeseries while they can be in use by another remote write without
deduplication

The panel will show how many ongoing select queries are processed by vmstorage
and should help to identify resource bottlenecks. See panel description for more details.

Allowing to select multiple instance IPs makes it much easier to view
metrics for longer periods of time in dynamic environments such as
Kubernetes. In k8s update will also cause IP to change making it harder
to use dashboard to check the status.

The new flag type is supposed to be used for specifying URL values which
could contain sensitive information such as auth tokens in GET params or
HTTP basic authentication.
The URL flag also allows loading its value from files if `file://`
prefix is specified. As example, the new flag type was used in
app/vmbackup as it requires specifying `authKey` param for making the
snapshot.

The cumulative number of active merges could be red herring
as it its value depends on the number of vmstorages.
For example, vmstorage could be added or removed and this will affect
the panel.
Or, each vmstorage could start a merging process (i.e. for downsampling)
and visiually it could look like a massive change.

We don't cover this corner case as it has low chance for reproduction.
Precisely, the requirements are following:
1. vmagent need to be configured with multiple identical `remoteWrite.url` flags;
2. At least one of the persistent queues need to be non-empty, which already
signalizes about issues with setup;
3. vmagent need to be restarted with removing of one of `remoteWrite.url` flags.
We do not document this case in vmagent.md as it seems to be a rare corner case
and its explanation will require too much of explanation and confuse users.

Starting from v1.99.0 vmalert could ignore anchors pointing to specific
rule groups if `search` param was present in URL.
This change makes anchors compatible with `search` param in UI.

Using `sh` or `console` formatting doesn't do word-breaking on render. This makes flags description
harder to read, as users need to scroll the web page horizontally.
Removing the formatting renders the description with normal word-breaking.
Stream aggregation may yield inaccurate results if it processes incomplete data.
This issue can arise when data is sourced from clients that maintain a queue of unsent data, such as Prometheus or vmagent.
If the queue isn't fully cleared within the aggregation interval, only a portion of the time series may be included in that period, leading to distorted calculations.
To mitigate this we add an option to ignore first N aggregation intervals. It is expected, that client queues
will be cleared during the time while aggregation ignores first N intervals and all subsequent aggregations
will be correct.
