Add the logging statements for when
application is doing implicit delete so if an user did a PUT on cloud region in which they implicitly delete 100 tenants, it would log the specific tenants that got deleted with depth all on tenants because a cloud region could also have thousands of other child objects and there is no reason to log that if we can just log the objects that were lost in the implicit delete process Issue-ID: AAI-2332 Change-Id: I8cd0c876670f8687b6485d3735f9f47e84c38286 Signed-off-by: Kajur, Harish (vk250x) <vk250x@att.com>
