No clear error message is shown in horizon when uploading image failes

[Gustavo Knüppe]

I have an image to be uploaded in glance with 15GB of size.
The upload is done by informing the URL.. So, horizon initiate a task in glance to upload the image.
The problem occurs when there is no enough free space in the directory where the image will be placed.
In this case, horizon simply change the task to "deleted".. No information is shown saying why it was deleted.
Horizon should better show error messages when tasks fails.

Fix proposed to branch: master

Sadly, the proposed fix just shows the exception to the user, which may lead to information disclosure.

IMHO we should fix it in a different way.

Agree. Actually i missed that ML topic.
I think that we should wait to fix this, because the message is also being translate on glance so won't be that easy.
Better to wait until glance expose some kind of error code or something like that.

In my case Havana setup, also tested image upload with insufficient disk space.

Uploaded image from Horizon UI source is ISO file, in bug description upload source is URL.
Failed to upload image but got generic Horizon "Something went wrong" error.

Upload from Glance CLI failed with an informative error message:
Image storage media is full: There is not enough disk space on the image storage media.
