> In FLINK-31593 we discovered an instability when generating the migration test data for 1.17 for {{StatefulJobSavepointMigrationITCase}} and {{StatefulJobWBroadcastStateMigrationITCase}}. According to the discussion in FLINK-31593, we concluded that it's caused by a non-determinism that's happening in the changelog backend code. As a workaround, we're going to disable the changelog backend in these tests for now.
> We're not touching 1.16 because it didn't appear in that branch. The non-determinism seems to kick in only when generating the checkpoint files. 
> For 1.17, we're gonna create a backport for consistency reasons because we have to enable it for the data generation.
