### Two main changes:
- 1、add minidump replay
- 2、change minidump serialization of statistic messages and some interface between main logic of nereids optimizer and minidump
### Use of nereids ut:
- 1、save minidump files:
Execute command by mysql-client:
```
set enable_nereids_planner=true;
set enable_minidump=true;
```
Execute sql in mysql-client
- 2、use nereids-ut script to execute directory:
```
cp -r ${DORIS_HOME}/minidump ${DORIS_HOME}/output/fe && cd ${DORIS_HOME}/output/fe
./nereids_ut --d ${directory_of_minidump_files}
```
### Refactor of minidump
- move statistics used serialization to serialization of input and serialize with catalogs
- generating minidump file only when enable_minidump flag is set, minidump module interactive with main optimizer only by :
serializeInputsToDumpFile(catalog, statistics, query) && serializeOutputsToDumpFile(outputplan).
