This gives us a place to initialize iobuf pools, specify subsystem dependencies, and execute RPCs to configure the sizes of the pools. We allow users to configure the size of the pools either through the options in spdk_bdev_opts or through the new RPC, iobuf_set_options. The second option has higher priority, so it will override the options set by the bdev layer.
