Currently, the official gcp-gcr orb doesn't have a way to specify the Dockerfile filename in its parameters. I'm talking about the
docker build ... -f Dockerfilename ...
option. This can be easily added to the current orb with a "dockerfile-name" parameter. And no, I'm not talking about the existing "path-to-dockerfile" option, which is nice but a totally different thing :)
