- Round staleness_interval durations to the upper number of seconds.
This should prevent from under-calculations for fractional staleness intervals.
- Rename stalenessInterval field at *AggrState structs into stalenessSecs, since it holds seconds.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4667
- Improve docs
- Hide `debug relabeling` column when -promscrape.dropOriginalLabels command-line flag is set
- Inline the code from the added template functions, since the code is harder to follow
with the template functions, especially when these functions have misleading names.
Also, these functions are used only in one place, e.g. they do not reduce the amounts of code.
- Hide `click to show original labels` title at `labels` column when original labels aren't available.
- Show the reason on whey original labels aren't available at /service-discovery page.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4597
- Parse protobuf if Content-Type isn't set to `application/json` - this behavior is documented at https://grafana.com/docs/loki/latest/api/#push-log-entries-to-loki
- Properly handle gzip'ped JSON requests. The `gzip` header must be read from `Content-Encoding` instead of `Content-Type` header
- Properly flush all the parsed logs with the explicit call to vlstorage.MustAddRows() at the end of query handler
- Check JSON field types more strictly.
- Allow parsing Loki timestamp as floating-point number. Such a timestamp can be generated by some clients,
which store timestamps in float64 instead of int64.
- Optimize parsing of Loki labels in Prometheus text exposition format.
- Simplify tests.
- Remove lib/slicesutil, since there are no more users for it.
- Update docs with missing info and fix various typos. For example, it should be enough to have `instance` and `job` labels
as stream fields in most Loki setups.
- Allow empty of missing timestamps in the ingested logs.
The current timestamp at VictoriaLogs side is then used for the ingested logs.
This simplifies debugging and testing of the provided HTTP-based data ingestion APIs.
The remaining MAJOR issue, which needs to be addressed: victoria-logs binary size increased from 13MB to 22MB
after adding support for Loki data ingestion protocol at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4482 .
This is because of shitty protobuf dependencies. They must be replaced with another protobuf implementation
similar to the one used at lib/prompb or lib/prompbmarshal .
Loki uses default labels format without "or" operator. This format can't create a list of LabelFilters, so only first set of LabelFilters should be used.

This eliminates the need in .(*T) casting for results obtained from Load()
Leave atomic.Value for map, since atomic.Pointer[map[...]...] makes double pointer to map,
because map is already a pointer type.
- Add `Active queries` chapter to VMUI docs
- Set `Content-Type: json` header inside promql.WriteActiveQueries() handler,
in order to be consistent with other request handlers called at app/vmselect/main.go
- Pass the request to promql.WriteActiveQueries() handler, so it can change its output
depending on the provided request params. This also improves consistency of
promql.WriteActiveQueries() args with other request hanlers at app/vmselect/main.go

* feat: add page to display a list of active queries (#4598)
* app/vmagent: code formatting
* fix: remove console

Using `job=~$job_storage` forces "Cache usage" panel to display only vmstorage caches, but there is a cache peresent at vmselect(`promql/rollupResult`).
Updated selector to match generic `$job` so that all caches will be displayed with an option to display per-job caches.
