ok, so the remaining two were also present in 
/usr/share/gitlab/config/feature_flags/development and were obsolete.

I confirmed the upgrade goes smooth after removing these and all other 
obsolete initializers. I have also implemented a check during build if 
any files in config is changed or not.

Moving 'config' directory out of /etc would be another option, but then 
that will need us to move files we would like users or package to be 
able to modify to /etc/gitlab manually (database.yml, gitlab.yml and 
some more .rb files like puma.rb). If anyone wants to give it a try, 
feel free.
