Does GitLab accept Federation?

I would like to make a federation sync between a GitBlit and a GitLab instance. Make federations with GitBlit is possible i know, but i don't find anything about federation in GitLab.

I tried to find :

• federations properties in gitlab.rb file
• federations fields in project or administrator settings
• hooks adaptater

Nothing found. Thanks for your answer

Federation is currently not supported, but there is a related discussion in GitLab's Issue Tracker.
