Refactored the data exchange operation.

  Unlike the original implementation needs two round messages, the redesigned
  block pull now needs only one round RPC, unless there is a RPC failure.
  The network address for peer StorageManager is cached locally, and will be
  updated once a block is created by a newly added peer.
