api/types/mount: bring back the mount type
The mount type is used across common GRPC services to express a deferred access of a filesystem. Right now, they are generated by snapshotters, but eventually, they can be passed for containers for creation at runtime. With this flow, we can separate the generation and use of a root container filesystem. Signed-off-by: Stephen J Day <stephen.day@docker.com>
