@dclarizio @mkanoor @gmcculloug please review/test copy feature for Automate Class, Instance and Method objects
one returns true/false if there are any unlocked domains and the other one returns all unlocked domains that can be used to populate pull down in UI. Called them unlocked to match with UI, where non-editable domains are being called as Locked Domains.
