Fix a problem where we need to abort due to a mapping failure, but we are in a managed environment and thus the orteds have not wired up. Thus, if we send the exit message across the routed network, the remote daemons won't have a way to relay the message along - and we won't exit.

If we are aborting, then set the flags so the HNP directly sends an exit command to each daemon. Make it the halt_vm command so the remote daemon doesn't try to relay it, but instead just exits without waiting for its routed children to exit first.
