The documentation team will not add 3rd party drivers, if you like to
see this documented read first
http://specs.openstack.org/openstack/docs-specs/specs/kilo/move-driver-docs.html
and then send a change for openstack-manuals.
If you do not plan on documenting this yourself and have nobody in
your organization to assign this to, let's mark this change as invalid.

Assigning back to Nikesh since he just asked on #openstack-doc about starting to work on this. I saw to late that both of you are in the same company,...
