Add gitlab badges

[thibaultduponchelle]

Hello,

This pull request adds support for gitlab badges (pipeline and coverage). Somebody opened an issue about it : #285

Currently the link is https://gitlab.com/$user_name/$repository_name/-/commits/master as documented in gitlab settings but we could imagine using also https://gitlab.com/$user_name/$repository_name/pipelines

Best regards.
