What do you think about extending org.ofono.ConnectionContext API with 
Add/RemoveProperty calls and PropertyAdded/Removed signals to allow 
platform/application specific properties of type string? Use cases 
include marking connections as preferred/default or assigning priorities 
to them, tracking the origin of the context (OTA, local provision or 
manually edited) and who knows what else.
