In Podman 1.6.3, we added support for anonymous volumes - fixing our old, broken support for named volumes that were created with containers. Unfortunately, this reused the database field we used for the old implementation, and toggled volume removal on for `podman run --rm` - so now, we were removing *named* volumes created with older versions of Podman. We can't modify these old volumes in the DB, so the next-safest thing to do is swap to a new field to indicate volumes should be removed. Problem: Volumes created with 1.6.3 and up until this lands, even anonymous volumes, will not be removed. However, this is safer than removing too many volumes, as we were doing before.
