Ability to hide Add to Boards menu items

[#1]

Description - Admins need the ability to govern their own instance. Showing menu items to users that they can never use just adds clutter and confusion to an already complex project management system. Admins should have the ability to show or hide EVERYTHING via layouts.

Why is this feature important to you - The Product Managers are more and more taking away our ability to manage what our users see by introducing "features" that the user will never use and are sometimes against company policy, that we as admins cannot hide from them.

How would you like the feature to work? - In the Layouts area, have a section for the "More" menu that allows us to hide or show the menu items individually (Add to Boards, Add to Iteration, Add to Kanban Board, Copy to..., Move to..., Duplicate)

Current Behaviour - No ability for admins to set up an instance that actually guides the user through the Standard Operating Procedure for their organisation, by showing what the user needs and hiding what will just confuse them and possibly lead them to inadvertently break the rules, ie, copying tasks from 3 year old jobs that are assigned to people who no longer work here and have hard dates from 3 years ago. Or trying to add to a Board when they have no access to any Boards, and as an admin, neither do I.

Same for Workstreams. I get a similar message to this for Boards - seems like a bad experience for the end-user to have an option available to them that isn't set up.

Allowing the Admins to hide or show these functions is crucial to support a great user experience.  Please add these.
