new "image" mount type
Add a new "image" mount type to `--mount`. The source of the mount is the name or ID of an image. The destination is the path inside the container. Image mounts further support an optional `rw,readwrite` parameter which if set to "true" will yield the mount writable inside the container. Note that no changes are propagated to the image mount on the host (which in any case is read only). Mounts are overlay mounts. To support read-only overlay mounts, vendor a non-release version of Buildah. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
