    Description

      In FLINK-10043 we have introduced builder pattern for RocksDBKeyedStateBackend and moved all necessary initialization of the backend into the builder, out of which the most important part is the restore operation. None of the backends could actually supply service before the restore operation is done, so it's native to make restore part of the building phase.

      In this JIRA we propose to make all backends follow the builder pattern. More specifically, create builders for HeapKeyedStateBackend and DefaultOperatorStateBackend and move their restore operations into the builders. Will create sub-tasks for each of them.
