Provide metric about "time to start of tests" on OSD
There is a plan to provide more metrics within SUSE, e.g. see https://confluence.suse.com/pages/viewpage.action?pageId=156401717#RalfUnger%E2%80%99sHome-Ideasby , and as we already use grafana we should be able to gather data from there.
- AC1: Time to start of tests on openqa.suse.de is provided automatically
Time to starting of tests on openqa.suse.de (how long does it take maximum that a test on openqa.suse.de starts; purpose: How users/teams/departments can integrate openQA tests into their own processes; data source: openQA database queries or existing data on https://stats.openqa-monitor.qa.suse.de;presentation: time ranges as statistical values, e.g. mean+-std, median, percentiles as numbers as well as graphs for progress)
