What is the version of your Accelerated Container Image

v1.0.2

What would you like to be added?

Layer deduplication needs to account for the underlying overlaybd-tool versions to avoid conversion mismatches.

Why is this needed for Accelerated Container Image?

As layer deduplication is currently unaware of any versioning for the underlying overlaybd tools, whenever overlaybd tools are upgraded, this can result in a situation where deduplication will try to reuse layers that are no longer compatible during conversion. This is also relevant for #249 and the non-user-space convertor, I think. We have been tracking this manually to prevent issues on our side, but a more programmatic approach is probably necessary in light of a few format issues we have discovered recently like containerd/overlaybd#301 and running with root vs not doing so. Overall, we want to discuss how to obtain versioning from overlaybd-tools to account for breaking changes and take this into account for the layer deduplication.
