Gorka Eguileor bb8771436e Add explanations on safe delete
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].

Volume drivers
==============
To use different volume drivers for the cinder-volume service, use the
parameters described in these sections.
These volume drivers are included in the `Block Storage repository
<https://opendev.org/openstack/cinder>`_. To set a volume
driver, use the ``volume_driver`` flag.
The default is:
.. code-block:: ini
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
Note that some third party storage systems may maintain more detailed
configuration documentation elsewhere. Contact your vendor for more information
if needed.
