Arguments:
1. start_height    (numeric, optional, default=0) block height where the rescan should start
2. stop_height     (numeric, optional) the last block height that should be scanned. If none is provided it will rescan up to the tip at return time of this call.

Result:
{
  "start_height"     (numeric) The block height where the rescan started (the requested height or 0)
  "stop_height"      (numeric) The height of the last rescanned block. May be null in rare cases if there was a reorg and the call didn't scan any blocks because they were already scanned in the background.
