Roman Khavronenko 1cb7037fc8 Vmalert metrics update (#1580)
* vmalert: remove `vmalert_execution_duration_seconds` metric

The summary for `vmalert_execution_duration_seconds` metric gives no additional
value comparing to `vmalert_iteration_duration_seconds` metric.

* vmalert: update config reload success metric properly

Previously, if there was unsuccessfull attempt to reload config and then
rollback to previous version - the metric remained set to 0.

* vmalert: add Grafana dashboard to overview application metrics

* docker: include vmalert target into list for scraping

* vmalert: extend notifier metrics with addr label

The change adds an `addr` label to metrics for alerts_sent and alerts_send_errors
to identify which exact address is having issues.
The according change was made to vmalert dashboard.

* vmalert: update documentation and docker environment for vmalert's dashboard

Mention Grafana's dashboard in vmalert's README in a new section #Monitoring.

Update docker-compose env to automatically add vmalert's dashboard.
Update docker-compose README with additional info about services.
