As we moved most of the creation of a BufferPool to be via the Streaming::pool() method, which uses a thread-local, it makes sense to start cleaning up the design and make it more modern C++. The above mentioned method would return a reference and you'd see loads of places use `auto &pool =` which is less than ideal. As the number of places where we actually instantiate a BufferPool goes down, the usage of some sort of smart pointer makes more sense. This now makes all APIs use BufferPool be wrapped in a shared_ptr.
