send data across hosts by utlizing metadata for underlying buffers of an object #381
Description
When sending data corresponding to a dataid from a host to other host we currently send data as the whole buffer. This currently crashes and is addresed in #376. As mentioned in issue comments a quick fix is underway and a better approach would be to use get shared buffer with metadata for underlying buffers of an object (s_data, raw_buffers, buffer_count) and then use send_complex_data.
