JobManagerHACheckpointRecoveryITCase still use ```LocalFlinkMiniCluster```
as it's default one. And we seem to be lost refactor it. And I dont think it
is a very easy work since in this ITCase, it use
```LocalFlinkMiniCluster.getLeaderGateway```. And in the new pattern of
```AbstractTestBase```. I dont know how to get that. ---
