coordination #80142: [saga][epic] Scale out: Redundant/load-balancing deployments of openQA, easy containers, containers on kubernetes
- AC1: minion job "scan_needles" have a sigterm handler to decide how to shut down in a clean way in a reasonable time
- AC2: Our minion job list on OSD and O3 do not show any "Job terminated unexpectedly" over multiple deployments (or service restarts) for "scan_needles"
- Implement sigterm handler for "scan_needles"
- Test on o3 and osd either by manually restarting openqa-gru multiple times or awaiting the result from multiple deployments and checking the minion dashboard, e.g. openqa.suse.de/minion/jobs?state=failed
