Task/remove local skopeo dependency

[henrjk]

At the moment this does not work, but I am not sure why.
Tag related commands from log excerpt gh-issue-662-docker-tags-not-working.log:

INFO  | skopeo copy docker://kind-registry.kind:5000/npjhnsyo/workspace-280637196:3cd3a01e4f8924ae17e4273543b5d6739ce3dc32 docker://kind-registry.kind:5000/npjhnsyo/workspace-280637196:latest

INFO  | skopeo copy docker://kind-registry.kind:5000/npjhnsyo/workspace-280637196:3cd3a01e4f8924ae17e4273543b5d6739ce3dc32 docker://kind-registry.kind:5000/npjhnsyo/workspace-280637196:cool

And then the local test command:

ods-package-image_test.go:143: docker [inspect --format={{.RepoTags}} localhost:5000/npjhnsyo/workspace-280637196:3cd3a01e4f8924ae17e4273543b5d6739ce3dc32]: exit status 1

exit status 1 means that the image is not found.

Now when I comment out the checkTags invocation, run the test and then locally issue the command it does find the image and associated manifest:

$docker inspect --format={{.RepoTags}} localhost:5000/lmxlhpwy/workspace-2456216427:3507037f00154c62410142e770df87fbed35db20

Closing as a consequence of #722. Unfortunately PRs cannot be transferred so a similar PR would need to be opened in ods-pipeline-image.
