Summary:
Refactor in two ways. First, expose members without getters as we will
need most of them in distributed. And this was always the sensible thing
to do. Second, add storage type values to deltas. This is also a
sensible thing to do, and it will be very beneficial in distributed. We
didn't do it before because name<->value type mappings aren't guaranteed
to be the same after recovery. A task has been added to address this
(preserve mappings in durability).
