Description

We noticed in FLINK-32678 that the toString() method of LeaderElectionDriver wasn't implemented with the FLINK-26522 changes. The legacy implementations actually provided a proper implementation. The MultipleComponentLeaderElectionDriver implementations (which we reused in FLINK-26522) didn't provide such a method.

See ZooKeeperLeaderElectionDriver.toString() and KubernetesLeaderElectionDriver.toString() for comparison.

I'm marking this as a critical because it's a regression. But I'm not marking it as a blocker because it's only affecting the log output.
