We currently configure only TimeoutStartSec, but probably it's not enough to prevent coredump timeout, since TimeoutStartSec is maximum waiting time for service startup, and there is another directive to specify maximum service running time (RuntimeMaxSec). To fix the problem, we should specify RunTimeMaxSec and TimeoutSec (it configures both TimeoutStartSec and TimeoutStopSec). Fixes #5430 Closes #12757
