### Prometheus querying API enhancements
VictoriaMetrics accepts optional `extra_label=<label_name>=<label_value>` query arg, which can be used for enforcing additional label filters for queries. For example,
`/api/v1/query_range?extra_label=user_id=123&query=<query>` would automatically add `{user_id="123"}` label filter to the given `<query>`. This functionality can be used
for limiting the scope of time series visible to the given tenant. It is expected that the `extra_label` query arg is automatically set by auth proxy sitting
in front of VictoriaMetrics. See [vmauth](https://docs.victoriametrics.com/vmauth.html) and [vmgateway](https://docs.victoriametrics.com/vmgateway.html) as examples of such proxies.
`/api/v1/query_range?extra_label=user_id=123&extra_label=group_id=456&query=<query>` would automatically add `{user_id="123",group_id="456"}` label filters to the given `<query>`. This functionality can be used for limiting the scope of time series visible to the given tenant. It is expected that the `extra_label` query args are automatically set by auth proxy sitting in front of VictoriaMetrics.

VictoriaMetrics accepts optional `extra_filters[]=series_selector` query arg, which can be used for enforcing arbitrary label filters for queries. For example,
`/api/v1/query_range?extra_filters[]={env=~"prod|staging",user="xyz"}&query=<query>` would automatically add `{env=~"prod|staging",user="xyz"}` label filters to the given `<query>`. This functionality can be used for limiting the scope of time series visible to the given tenant. It is expected that the `extra_filters[]` query args are automatically set by auth proxy sitting in front of VictoriaMetrics. See [vmauth](https://docs.victoriametrics.com/vmauth.html) and [vmgateway](https://docs.victoriametrics.com/vmgateway.html) as examples of such proxies.
VictoriaMetrics accepts relative times in `time`, `start` and `end` query args additionally to unix timestamps and [RFC3339](https://www.ietf.org/rfc/rfc3339.txt).
For example, the following query would return data for the last 30 minutes: `/api/v1/query_range?start=-30m&query=...`.

VictoriaMetrics supports `__graphite__` pseudo-label for filtering time series with Graphite-compatible filters in [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html).

## tip
* FEATURE: accept optional `extra_filters[]=series_selector` query args at Prometheus query APIs additionally to `extra_label` query args. This allows enforcing additional filters for all the Prometheus query APIs by using [vmgateway](https://docs.victoriametrics.com/vmgateway.html) or [vmauth](https://docs.victoriametrics.com/vmauth.html). See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1863).
* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth.html): allow specifying `http` and `https` urls in `-auth.config` command-line flag. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1898). Thanks for @TFM93 .
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): allow specifying `http` and `https` urls in the following command-line flags: `-promscrape.config`, `-remoteWrite.relabelConfig` and `-remoteWrite.urlRelabelConfig`.
* FEATURE: vminsert: allow specifying `http` and `https` urls in `-relabelConfig` command-line flag.

`/api/v1/query_range?extra_filters[]={env=~"prod|staging",user="xyz"}&query=<query>` would automatically add `{env=~"prod|staging",user="xyz"}` label filters to the given `<query>`. This functionality can be used for limiting the scope of time series visible to the given tenant. It is expected that the `extra_filters[]` query args are automatically set by auth proxy sitting in front of VictoriaMetrics. See [vmauth](https://docs.victoriametrics.com/vmauth.html) and [vmgateway](https://docs.victoriametrics.com/vmgateway.html) as examples of such proxies.
VictoriaMetrics accepts relative times in `time`, `start` and `end` query args additionally to unix timestamps and [RFC3339](https://www.ietf.org/rfc/rfc3339.txt).
For example, the following query would return data for the last 30 minutes: `/api/v1/query_range?start=-30m&query=...`.
