Cloned from launchpad blueprint https://blueprints.launchpad.net/cinder/+spec/cinder-volume-driver-optional-iscsi-support.

Description:

Cinder supports a number of protocols across its volume drivers. Not all
hypervisors support all of these protocols while most hypervisors, if not all,
support iscsi. To this end, this blueprint proposes to add a common means of
adding optional iscsi support to any driver.

As an example, the Ceph RBD driver exports volumes using the rbd protocol which,
at the time of writing is not supported by all hypervisors. Optional
iscsi support would allow the Ceph RBD driver to export volumes using iscsi to
hypervisors that do not support rbd.
