[oCIS] Add Transparent Sharing Roles for the Personal Space

[micbar]

Description

The sharing from a personal space and from individual files / folders currently does not give the permission "ListGrants"

We will add a new set of Roles which all have the permission "List Grants"

@micbar @tbsbdr Should the existing roles Editor - new Editor and Viewer - new Viewer be mutually exclusive or can they be enabled simultaneously?

Can be enabled simultaneously.
