2b4d3effad app/vmagent/remotewrite: add "X-Prometheus-Remote-Write-Version: 0.1.0" http header to remote_write request 
This header is required by Cortex (and, probably, other remote storage systems).
See 9c1f44d090/docs/apis.md (remote-api) .

  in order to apply the most specific filters first.

  (usually this are negative filters or regexp filters).

253844b74c deployment/docker: run docker apps under default user (0, root) in order to preserve backwards compatibility 
If docker app is upgraded from root to non-root, then the data pointed by `-storageDataPath` or similar flags
becomes denied to non-root user after the upgrade. This breaks upgrade path. So revert back to default root user
for docker apps.

Users may explicitly execute `docker run --user <non_root_user>` for running docker apps under non-root user.

Update dashboard according to new Grafana version and some metric renames. (#392) 
The list of changes is following:
* fix Uptime panel column styles according to changes introduced in 6.7 Grafana version
* fix panel `vminsert/Rows per insert` due to metric rename - see #336
* change default datasource to VictoriaMetrics since dashboard now uses MetricsQL for `vminsert/Rows per insert` panel

58cb7fc476 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.

bf1869d33d 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.
