Description of problem:
Uploading different snapshot disks of the same disk look like the same event as the snapshot disk name is the same.

So it looks like the same operation was performed multiple times.
Maybe add also the disk id in the event will make it more clear.

In my case I got for 2 different disk snapshots of the same disk(disk_TestCase24989_1612010196) the following events(:
EVENT_ID: TRANSFER_IMAGE_SUCCEEDED(1,032), Image Upload with disk disk_TestCase24989_1612010196 succeeded.

EVENT_ID: TRANSFER_IMAGE_SUCCEEDED(1,032), Image Download with disk disk_TestCase24989_1612010196 succeeded.


Version-Release number of selected component (if applicable):
ovirt engine - 4.3.0-0.2.master.20181128141347.git38908dd.el7

How reproducible:
100%

Steps to Reproduce:
1.upload/download multiple snapshot disks belonging to the same disk named 'disk1'

Actual results:
Uploading different snapshot disks of the same disk look like the same event as the snapshot disk name is the same.

So it looks like the same operation was performed multiple times.
Maybe add also the disk id in the event will make it more clear.

EVENT_ID: TRANSFER_IMAGE_SUCCEEDED(1,032), Image Download with disk disk_TestCase24989_1612010196 succeeded.

Expected results:
I think we should add a clear event message for snapshot disk upload/download like:
"Uploading/Downloading snapshot disk id X"

In this way, it's clear what you are downloading/uploading in a unique way by using snapshot disk id and not the confusing disk name which is the same in this case.
