Add feature flag for realname
Closes #318
I add real_name_system to make feature flag work. @icbd Could you please help review and give some suggestions.
And there are two points not resolve yet, see the comment below.
These 2 points had been solved and I will create a MR to upstream
The upsteam MR gitlab-org/gitlab!73424 (merged)
