Disable checkpointing of containers started with --rm
Trying to checkpoint a container started with --rm works, but it makes no sense as the container, including the checkpoint, will be deleted after writing the checkpoint. This commit inhibits checkpointing containers started with '--rm' unless '--export' is used. If the checkpoint is exported it can easily be restored from the exported checkpoint, even if '--rm' is used. To restore a container from a checkpoint it is even necessary to manually run 'podman rm' if the container is not started with '--rm'. Signed-off-by: Adrian Reber <areber@redhat.com>
