Move instance_resize code paths to BDM objects

Make both resize_instance and confirm_resize compute manager methods use
BDM objects. This is achieved by moving the helper method
_terminate_volume_connections to use BDM objects.
This patch also avoids unnecessary calls to conductor as now all helper
methods used allow for passing the already dug up BDM list.
