getblockfrompeer "blockhash" peer_id

Attempt to fetch block from a given peer.

We must have the header for this block, e.g. using submitheader.
Subsequent calls for the same block and a new peer will cause the response from the previous peer to be ignored.

Returns an empty JSON object if the request was successfully scheduled.

2. peer_id      (numeric, required) The peer to fetch it from (see getpeerinfo for peer IDs)
