09fbff57fc introduced new knob
for such functionality. However, that seems unnecessary.
The mount option string is ubiquitous in that all of fstab,
kernel cmdline, credentials, systemd-mount, ... speak it.
And we already have x-systemd.device-bound= that's parsed
by pid1 instead of fstab-generator. It feels hence more natural
for graceful options to be an extension of that, rather than
its own property.
There's also one nice side effect that the setting itself
is now more graceful for systemd versions not supporting
such feature.
