When provisioning a Scylla docker image with --developer-mode 0 (disabled)
scylla_raid_setup is not invoked. As a consequence the "data" directory is not
created and scylla_io_setup fails (steps to reproduce and error message provided
at the end).
This patch adds the same verifications present in scylla_io_setup to docker's
scyllasetup.py and creates the data directory in the case it is not present.

Steps to reproduce on AWS i3.2xlarge with Ubuntu 16.04:
sudo -s
apt update && apt upgrade -y && apt-get install docker.io -y
mdadm --create --verbose --force --run /dev/md0 --level=0 -c1024 --raid-devices=1 /dev/nvme0n1
mkfs.xfs /dev/md0 -f -K
mkdir /var/lib/scylla
mount -t xfs /dev/md0 /var/lib/scylla
docker run --name some-scylla \
--volume /var/lib/scylla:/var/lib/scylla \
-p 9042:9042 -p 7000:7000 -p 7001:7001 -p 7199:7199 \
-p 9160:9160 -p 9180:9180 -p 10000:10000 \
-d scylladb/scylla --overprovisioned 1 --developer-mode 0
docker logs some-scylla
running: (['/usr/lib/scylla/scylla_dev_mode_setup', '--developer-mode', '0'],)
running: (['/usr/lib/scylla/scylla_io_setup'],)

ERROR:root:/var/lib/scylla/data did not pass validation tests, it may not be on XFS and/or has limited disk space.
This is a non-supported setup, and performance is expected to be very bad.
For better performance, placing your data on XFS-formatted directories is required.
To override this error, enable developer mode as follow:
sudo /usr/lib/scylla/scylla_dev_mode_setup --developer-mode 1
failed!
