we'd like to support bs set throttle command in curve tool

• The implementation of the old tool is here：

  curve/src/tools/namespace_tool_core.cpp

  Lines 187 to 212 in 8d6caf7

  	int NameSpaceToolCore::UpdateFileThrottle(const std::string& fileName,
  	const std::string& throttleType,
  	const uint64_t limit,
  	const int64_t burst,
  	const int64_t burstLength) {
  	curve::mds::ThrottleType type;
  	if (!curve::mds::ThrottleType_Parse(throttleType, &type)) {
  	std::cout
  	<< "Parse throttle type '" << throttleType
  	<< "' failed, only support "
  	"IOPS_TOTAL|IOPS_READ|IOPS_WRITE|BPS_TOTAL|BPS_READ|BPS_WRITE"
  	<< std::endl;
  	return -1;
  	}
  	curve::mds::ThrottleParams params;
  	params.set_limit(limit);
  	params.set_type(type);
  	if (burst >= 0) {
  	if (burst < limit) {
  	std::cout << "burst should greater equal to limit" << std::endl;
  	return -1;
  	}
  	params.set_burst(burst);
  	params.set_burstlength(burstLength > 0 ? burstLength : 1);
  	}

• The old command input and out put:
