Title: Preserve image properties on update

* By default, image properties should not be deleted on image update.
* A user can specify --purge-props through the CLI or purge_props
as a keyword argument to ImageManager.update to override the default
behavior and force properties to be deleted.
* Fixes bug 1022758
