How do you write the context configuration code for the flink execution
environment? Like this：
```
final StreamExecutionEnvironment env =
StreamExecutionEnvironment.getExecutionEnvironment();
env.enableCheckpointing(60000, EXACTLY_ONCE);
env.setStateBackend(new HashMapStateBackend());
final CheckpointConfig checkpointConfig = env.getCheckpointConfig();
checkpointConfig.setMinPauseBetweenCheckpoints(500);
checkpointConfig.setCheckpointTimeout(60000);
checkpointConfig.setTolerableCheckpointFailureNumber(2);
checkpointConfig.setMaxConcurrentCheckpoints(1);
checkpointConfig.enableUnalignedCheckpoints();
checkpointConfig.enableExternalizedCheckpoints(
CheckpointConfig.ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION);
checkpointConfig.setCheckpointStorage(path);
.....
```
