When we can't reach quorum, we were waiting forever and never sending
the systemd notify message. As a result, systemd would eventually time out
and restart the etcd process which likely would make the unhealthy cluster
in an even worse state

This should aid in debugging test flakes, especially in tests where the process is restarted very often and thus changes its pid.
Now it's a lot easier to grep for different members, also when different tests fail at the same time.
The test TestDowngradeUpgradeClusterOf3 as mentioned in #13167 is a good example for that.
