[BugFix] Fix rows and bytes rate statistic in routine load

[wyb]

Why I'm doing:

summary.put("receivedBytesRate", Long.valueOf(receivedBytes / totalTaskExcutionTimeMs * 1000));
summary.put("loadRowsRate", Long.valueOf((totalRows - errorRows - unselectedRows) / totalTaskExcutionTimeMs * 1000));

if receivedBytes < totalTaskExcutionTimeMs, the result is 0

What I'm doing:

multiply by 1000 first
