Description

As part of FLINK-20695 we introduced a new method to the HighAvailabilityServices.cleanupJobData interface. Since this method has not default implementation it is currently breaking change. Since Flink allows to implement custom Ha services using this interface, I suggest adding a default implementation for this method.
