Scneario: Have 2 Projects/Tenants: 1. ProjectA / userA 2. ProjectB / userB

UserA from ProjectA performs following steps: 1. Create a block device volume("My-Vol1") and populates some data 2. Creates a snapshot ("My-Vol1-snapshot1") of the volume "My-Vol1"

Now UserA from ProjectA wants to grant permission to UserB in projectB to this newly created snapshot ("My-Vol1-snapshot1") so that userB can than create a new volume using this snapshot and attach to a server running in ProjectB
