We keep seeing people concerned about data leakage and thorough deletion
of data from volumes on volume deletion [1][2], and Cinder currently
only worries about the data leakage, not the stealing of the physical
disks.
In order to clarify this for administrators and to reduce the number of
specs proposed to address this issue we are adding additional
documentation on security aspects as well as data leakage.
This patch was decided as an action from the discussion during the
Wallaby PTG [3].
