Minimize RAM usage of disk uploader when extracing big disks #547
Description
There can be big disk images. The size of them can be 10-100gb (e.g. in Windows VMs). May be need to perform scalability testing in order to ensure that existing functionality can deal with big disk images.
@akalenyu said that CDI is using below 1gb of RAM to import disk images from container registry, and in our case, it could be also applied.
