avocado.utils.vmimage.Image.from_parameters() hangs on network even if base image is in cache

[lukasstraub2]

Describe the bug
vmimage.Image.from_parameters() takes a long time for me, sometimes more than a minute, because network requests get ratelimited. Even if the image is in cache already. It also does not work offline for this reason.

Steps to reproduce
Disable your internet connection and call vmimage.Image.from_parameters() to request an image that is in cache already.

Expected behavior
It should finish instantly.

Current behavior
It hangs.
