URL: https://github.com/apache/hudi/pull/7189
### Change Logs
Add support for write success file to a finished partition in flink
streaming append write:
1. add a SuccessFileWriteFunction class which aimed at to write succe file
to partition, and add operator state to store the active partitions and
finished partitions to avoid them lost data while failover;
2. add flink options
`partition.write-success-file.enable` to switch whether enable this feature
in flink job；
`partition.write-success-file.delay` the delay of write success file;
``
3. change `HoodieTableSink` class, support to extract partition path from
streaming record, and emit to extract.
4. Use DefaultPartTimeExtractor in flink to extract the timestamp from
partition path, and adapt it in different flink versions (1.13x, 1.14x, 1.15x)
### Impact
Used in flink sql job consume from mq and write into hudi, if you want to
use this feature, set the options as below in hudi sink table ddl
```
create table test_out(
id bigint,
data string,
`day` string,
`hour` string
) partitioned by (`day`, `hour`)
with (
'connector' = 'hudi',
'partition.time-extractor.timestamp-pattern' = '$day $hour:00:00',
'partition.write-success-file.delay' = '1h', -- if the table partitioned
by hour, set the delay 1h; if the table partitioned by day, set the delay 1day;
'partition.write-success-file.enable' = 'true',
'table.type' = 'COPY_ON_WRITE',
'write.operation' = 'insert',
'write.tasks' = '5',
'write.insert.cluster' = 'false',
'metadata.enabled' = 'true',
'path' = 'hdfs://testcluster/user/test/hudi/test_out14',
);
```
