3c7c71a49c app/vmselect: adjust label_map() handling for corner cases 
The following corner cases now supported:
* label_map(q, "label", "", "foo") - adds `label="foo"` to series with missing `label`
* label_map(q, "label", "foo", "") - removes `label="foo"` from series

All the unmatched labels are kept unchanged.

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.
