osd: make osd_fast_shutdown_notify_mon option true by default

osd_fast_shutdown_notify_mon option is false by default. So users suffer
from error log flood, slow ops, and the long I/O timeouts on voluntary OS
shutdown before they are aware of the existence of this option. Let's
make this option true by default.
