Would be great to have the possibility to copy tags of an image. Something like this to copy tags to the destination with the image:
gcrane copy --preserve-tags repo.com/myimage:1.0.0 dest-repo.com

or to add tags while copying:

gcrane copy --preserve-tags --tag latest --tag 1.0 --tag 1 repo.com/myimage:1.0.0 dest-repo.com
