I think this PR can be split into two: One PR which refactors the tardev-snapshotter build parts without modifying the pod sandboxing build parts. Another PR which changes the pod sandboxing build path to build with tardev-snapshotter included and with a virtio-blk secondary configuration included

See comments, vote to split. On hold for now.
