Since the Linux system abort booting when it fails to mount fstab entries,
user may not able to see an error message when we use fstab to mount
/var/lib/scylla on AMI.
Instead of abort booting, we can just abort to start scylla-server.service
when RAID volume is not mounted, using RequiresMountsFor directive of systemd
unit file.
