ceph-volume fails when sudo is not installed
On systems where sudo is not installed, ceph-volume fails. Debian 9.1 / Python 2.7.13
root@sumi1:~# ceph-volume lvm create --bluestore --data /dev/sdh --> OSError: [Errno 2] No such file or directory
As sudo is not installed by default on some systems, ceph-volume should be able to run without. This would make it possible to run it as root on systems w/o sudo and by user intention with sudo (eg. sudo ceph-volume ...).
