* lib/promscrape/discovery/kubernetes: fix leaking api watcher
goroutine which was polling k8s API had no execution control. This leaded to leaking goroutines during config reload.

* lib/promscrape/discovery/kubernetes: remove waitgroup sync for goroutines polling API server
This is unnecessary since context will is cancelled and new requests will not be sent. Also, using waitgroup will increase time required to perform reload which might result in missed scrapes.

* lib/backup: force copying of parts.json
Copying of parts.json is required because `part.key()` comparison can create same key value for files with different contents. This will result in inconsistent backup being created or restored.

previously vminsert doesn't check readOnly state for vmstorage, since check was never performed for nil buffer
In this case every 30 second storage node loss readonly state and received some data.
It caused re-routing and possible slow down for ingestion

Initially, stream parse mode was reading data from response and parsing it on flight. This was causing longer delay to read the whole response and required increasing timeout value to allow data processing while reading. So that 908e35affd increased timeout value to fix this.
But after 74c00a8762 response in stream parse mode is saved into memory and then parsed eliminating necessity of having timeout value higher that for usual scrape.

vmagent: properly add extra labels before sending data to remote storage

are pushed to `remoteWrite.url` after all relabelings, including stream aggregation relabelings (#4247)

Opentelemetry format allows histograms with non-counter buckets. In this case it makes no sense to add buckets into database
and save only counter with _count suffix.
It could be used as gauge.

* lib/promrelabel: fix relabeling if clause being applied to labels outside of current context
Relabeling is applied to each metric row separately, but in order to lower amount of memory allocations it is reusing labels.
Functions which are working on current metric row labels are supposed to use only current metric labels by using provided offset, but if clause matcher was using the whole labels set instead of local metrics.
This leaded to invalid relabeling results such as one described here: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4806
