`librbd.OpenImageById()` works if the image is in the trash, so it makes it possible to get the parent of the image. Signed-off-by: Niels de Vos <ndevos@ibm.com>
When a new volume is not created yet, the ImageID should not be set to the ID of the snapshot. Signed-off-by: Niels de Vos <ndevos@ibm.com>
In some places the ImageID is used as the ID of the parent. That is very confusing and prone to errors. Instead, fetch the right ImageID where possible, and set ParentID for referencing to parent images. Signed-off-by: Niels de Vos <ndevos@ibm.com>

If the RBD-image is deleted already, the DeleteVolume CSI procedure is expected to report success (as it should be idempotent). In case the returned error indicates "RBD image not found", the error is ignored and the DeleteVolume procedure continues. Signed-off-by: Niels de Vos <ndevos@ibm.com>
