attaching volumes will set instance_uuid instantly
This change allows the instance_uuid field to be set instantly when
beginning an attach action. The user will no longer have to wait for the
attachment to be complete to know what it is attaching to. If attaching
fails on the driver layer, we got error state and keep the instance_uuid
set for troubleshooting purposes.
