So that users can specify two docker image builds for the same
repository, but with different tags, ensure that the temporary
change_ tag attached to the image also includes the final tag
name.
This allows this configuration to work:
docker_images:
- repository: foo/image
context: opensuse
tags:
- opensuse-latest
- repository: foo/image
context: ubuntu
tags:
- ubuntu-latest
