This patch introduces the changes required by osd configuration tasks to
support Nautilus release:
- ceph-disk has been removed and replaced by ceph-volume
- OSDs can not be based on directories anymore, only disks or vg/lv
paths.
- udev configuration is not needed since some releases back.
To pass CI, this job requires to merge [1] and viceversa. To solve
chicken-and-egg, I'm setting p-o-i jobs as non-voting in this patch.
I'll make them voting again after merging both [1] and this one.
