Ability to Restrict Add-ons/Macros to Groups/Users in Confluence

This is a feature request to add the ability to restrict the usage of specific add-ons according to the granted permissions to groups/individual users in Confluence.

For example, a new plugin was created for administration purposes and only the administrators should be able to work with the information for this add-on. Then, it could be restricted only to the 'confluence-administrators' group to see it in the drop down for macros. Like having a list under the Manage Add-ons option in Confluence.
