we'd like to support bs scan status command in curve tool

• The implementation of the old tool is here：

  curve/src/tools/status_tool.cpp

  Lines 728 to 769 in 8d6caf7

  	int StatusTool::ScanStatusCmd() {
  	if (FLAGS_logicalPoolId != 0 && FLAGS_copysetId != 0) {
  	CopysetInfo copysetInfo;
  	auto lpid = FLAGS_logicalPoolId;
  	auto copysetId = FLAGS_copysetId;
  	if (mdsClient_->GetCopyset(lpid, copysetId, &copysetInfo) != 0) {
  	std::cout << "GetCopyset fail!" << std::endl;
  	return -1;
  	}
  	std::cout
  	<< "Scan status for copyset("
  	<< lpid << "," << copysetId << "):" << std::endl
  	<< " scaning=" << copysetInfo.scaning()
  	<< " lastScanSec=" << copysetInfo.lastscansec()
  	<< " lastScanConsistent=" << copysetInfo.lastscanconsistent()
  	<< std::endl;
  	return 0;
  	}
  	std::vector<CopysetInfo> copysetInfos;
  	if (mdsClient_->GetCopySetsInCluster(&copysetInfos, true) != 0) {
  	std::cout << "GetCopySetsInCluster fail!" << std::endl;
  	return -1;
  	}
  	int count = 0;
  	std::cout << "Scaning copysets: " << copysetInfos.size();
  	for (auto& copysetInfo : copysetInfos) {
  	if (count % 5 == 0) {
  	std::cout << std::endl;
  	}
  	std::cout << " (" << copysetInfo.logicalpoolid()
  	<< "," << copysetInfo.copysetid() << ")";
  	count++;
  	}
  	std::cout << std::endl;
  	return 0;
  	}
