Add --ignore-rootfs option for checkpoint/restore
The newly added functionality to include the container's root
file-system changes into the checkpoint archive can now be explicitly
disabled. Either during checkpoint or during restore.
If a container changes a lot of files during its runtime it might be
more effective to migrated the root file-system changes in some other
way and to not needlessly increase the size of the checkpoint archive.
If a checkpoint archive does not contain the root file-system changes
information it will automatically be skipped. If the root file-system
changes are part of the checkpoint archive it is also possible to tell
Podman to ignore these changes.
