Feature request: Project api does not have emails_disabled implemented

org.gitlab4j.api.models.Project class does not have a field to modify "Disable email notifications" setting (Settings - General - Visibility, project features, permissions - "Disable email notifications" checkbox). 

In API the field is called "emails_disabled".

Can it be added please?

Probably I can do it?
