Summary: The only use of this class was to implement the SharedCluster of ValueObjects. However, the same functionality can be implemented using a regular std::shared_ptr, and its little-known "sub-object pointer" feature, where the pointer can point to one thing, but actually delete something else when it goes out of scope. This patch reimplements SharedCluster using this feature -- SharedClusterPointer::GetObject now returns a std::shared_pointer which points to the ValueObject, but actually owns the whole cluster. The only change I needed to make here is that now the SharedCluster object needs to be created before the root ValueObject. This means that all private ValueObject constructors get a ClusterManager argument, and their static Create functions do the create-a-manager-and-pass-it-to-value-object dance.
