Is there a way for a snap to opt out of automatic snapshots? In the case of MicroK8s the removal of the snap is often impossible since the snap may have accumulated several GB of images under SNAP_COMMON. Users report removing the snap takes hours before they run out of disk space. The
snap remove --purge is nice to have. It would be great if the snap could specify in its
snapcraft.yaml some paths to ignore during snapshot.
