This patch includes the Cinder changes needed to support volume multiple attaches. Nova and python-cinderclient also need patches associated to provide support for multiple attachments. This adds the multiattach flag to volumes. When a volume is created, a multiattach flag can be set, which allows a volume to be attached to more than one Nova instance or host. If the multiattach flag is not set on a volume, it cannot be attached to more than one Nova instance or host Each volume attachment is tracked in a new volume_attachment table. The attachment id is the unique identifier for each attachment to an instance or host. When a volume is to be detached the attachment uuid must be passed in to the detach call in order to determine which attachment should be removed. Since a volume can be attached to an instance and a host, the attachment id is used as the attachment identifier.
