Passing arguments to docker build

[Agrabski]

🚀 Feature Description

As a developer, I'd like to be able to provide additional arguments passed to docker build, when using the generate command. This would allow, for instance, passing --add-hosts argument. My company has an internal feed for npm packages and building the docker image for our nodejs app requires access to this repository by its name.
A workaround is to manually add the entry to the underlying virtual machines /etc/hosts file. However, in my opinion, this is an suboptimal solution

✔ Goals

• Add cli option to generate command, that allows adding arguments to docker build command
• Add option to persist these additional arguments in aspirate-state.json
