[SDKs] arv-copy fails to copy a Docker image specified with repo:tag syntax
Since docker uses colons to specify tags, when writing pipeline templates, a developer will use "docker_image":"repo/image:tag" in runtime_constraints. This format breaks when using arv copy, since docker images and tags are space separated in arvados, causing the relevant docker images to not be copied.

I'll make a separate issue for the
arv keep docker request.
I'm going out on a limb and saying this is probably .5 points because it should just be a parsing error.

Nevermind, confirmed the bug is in fact in arv-copy. Probably because this syntax wasn't expected to work: we have a separate docker_image_tag constraint to specify the tag. But we should probably move to more the way you're doing it.
(Developers: See copy_docker_images in arv_copy.py. We can extend this backward-compatibly by trying to parse the tag out from docker_image when docker_image_tag isn't set.
latest should remain the ultimate default.)
