pack: Allow setting a custom image tag for Docker images
Previously, the image repository name was automatically computed from the packages in the manifest without allowing the user to set a custom one. As such, changing the packages in the manifest would result in a new image name. Thereby requiring updating documentation et cetera when using `docker load` directory on the resulting image. Inspired by `docker build -t`, this commit adds a new Docker-specific option to `guix pack` which allows setting a custom repository name for the resulting image. If this option is not specified, pack falls back to computing the name from the manifest. Therefore, this change is entirely backwards compatible. * guix/scripts/pack.scm (guix-pack): Add --image-tag option. (%docker-format-options): New constant. (show-docker-format-options): New procedure. (show-docker-format-options/detailed): New procedure. (docker-image): Allow setting a custom repository name for the created docker image via extra-options. * doc/guix.texi (Invoking guix pack)[docker]: Document --image-tag option.
