  in order to apply the most specific filters first.

499594f421 lib/promscrape: allow overriding external_labels as Prometheus does 
Prometheus docs at https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config say:

> In communication with external systems, they are always applied only
> when a time series does not have a given label yet and are ignored otherwise.

Though this may result in consistency chaos when scrape targets override `external_labels`,
let's stick with Prometheus behavior for the sake of backwards compatibility.

There is last resort in vmagent with `-remoteWrite.label`, which consistently
sets the configured labels to all the metrics before sending them to remote storage.

164278151f app/vmselect/promql: add aggr_over_time(("aggr_func1", "aggr_func2", ...), m[d]) function 
This function can be used for simultaneous calculating of multiple `aggr_func*` functions
that accept range vector. For example, `aggr_over_time(("min_over_time", "max_over_time"), m[d])`
would calculate `min_over_time` and `max_over_time` for `m[d]`.

`runTransactions` call issues async deletions for transaction files. The previously issued transaction deletions
can race with the next call to `runTransactions`. Prevent this by waiting until all the pending transaction
deletions are funished in the beginning of `runTransactions`. Also make sure that all the pending transaction
deletions are finished before returning from `runTransactions`.

The metricID->metricName entry can be missing in the indexdb after unclean shutdown
when only a part of entries for new time series is written into indexdb.

Recover from such a situation by removing the broken metricID. New metricID
will be automatically created for time series with the given metricName
when new data point will arive to it.

a7125a5b7b lib/backup: remove flock.lock file in empty dirs 
This fixes an issue when VictoriaMetrics doesn't see the restored data after the following operations:

1. Stop VictoriaMetrics.
2. Delete `<-storageDataPath>` dir.
3. Start VictoriaMetrics, then stop it.
4. Restore data from backup with `vmrestore`.
5. Start VictoriaMetrics.

`vmrestore` didn't delete properly empty dirs in `<-storageDataPath>/indexdb` because of the remaining `flock.lock` files in these dirs.
