In order to better grasp the performance of database in practical application,
we add a module to count the time-consuming of each operation. This module can
statistic the avg time-consuming of each operation and the proportion of each
operation fall into a time range.A output example is in below. This module uses
asynchronous operation to reduce the impact on the normal speed of the
database.The queue size is controlled by a param in iotdb-engine.properties,
which is 'performance_stat_memory_in_kb'. The output is in log_measure.log
file.
