This expects a GPG key fingerprint as a value of the argument (though
other key identification methods, like mitr@volny.cz, happen to work).
Do we need to namespace this (gpg:…)?
Note that this is unusable at the moment because only the dir: backend
implements storing signatures, and this backend does can not determine
the canonical Docker reference to use as a signed image identity.
This copies an image from ImageSource to ImageDestination, e.g.
skopeo copy atomic:mitr/busybox:latest dir:t-down # pull
skopeo copy dir:t-up atomic:mitr/busybox:latest # push
