fix: separate signals for passive, active, and forced shutdown
`SIGTERM`: Passive shutdown stopping provisioner daemons from accepting newjobs but waiting for existing jobs to successfully complete.`SIGINT` (old existing behavior): Notify provisioner daemons to cancel in-flight jobs, wait 5s for jobs to be exited, then force quit.`SIGKILL`: Untouched from before, will force-quit.
