Count contributions made by a user to GitLab

[wkyoshida]

Hey there! :wave:

This issue would be for a feature.

As more Wikimedia development moves to https://gitlab.wikimedia.org/, it could be nice to have the ability to aggregate contribution data for https://gitlab.wikimedia.org/ also in WikiContrib. For this there would of course be two parts - generally, the API integration with GitLab in the back-end and then the inclusion of GitLab in the front-end as an option to the query and the resulting graph. Let me know if more information is needed.

Cheers! wkyoshida
