The purpose of this spec is to change the behavior of the volume extend
API to allow an attached volume to be extended. This allows the
volume driver to extend the existing volume without first requiring
that the volume be detached and put back in the available state.
Nova will be asked to act on the size increase and to allow
the instance to have access to the added space after the volume
driver extends the volume.
