David Leadbeater 31a6449734 Add capability for snapshotters to declare support for UID remapping
This allows user namespace support to progress, either by allowing
snapshotters to deal with ownership, or falling back to containerd doing
a recursive chown.

In the future, when snapshotters implement idmap mounts, they should
report the "remap-ids" capability.
