Modeler - move repository of public in-cloud models to github

[jangorecki]

FR to move in-cloud public models repository to github.

• save model to public cloud just by pushing PR
• all models are under version control so models evolution over time can be also easily tracked and reproduced.
• people can contribute to the same model by pushing PR

Now that our Google backend died, this seems like a good option. I just need to figure out how to do this without exposing credentials... Do you know how? :)

AFAIK there is no need for credentials. At least in GitLab. Making new repo for models and setting up CI so models are published after merging PRs. There should be a github way for that as well.
