Description

Sometimes when we push images to our docker registries, the images
don't always make it in every location they should be (by accident, error, etc).

When this happens, it makes said images appear available, but are actually
still inaccessible. The bigger issue arises when that image is used by another
repo as well (such as a base image).

When this issue occurs, we get unexpected outtages. Someone will try to pull
from another repo that shares that layer, Crane goes looking for it, the first
place it sees it should be is in the broken repo, it checks, can't grab the image
and gives up.

I'm requesting that Crane try again, if it doesn't find the image the first time,
look for the next place it exists and try there. It would still be helpful to see
output somewhere that it failed to pull an image so we know there's an issue, but this
would stop errors in one repo affecting the rest of the registry.
