Overall, the changes and the tests look very good. There are some `TODO`s
left in the code, what about those?

> Key: FLINK-5146
> URL: https://issues.apache.org/jira/browse/FLINK-5146
> Project: Flink
> Issue Type: Improvement
> Components: State Backends, Checkpointing
> Reporter: Stefan Richter
> Assignee: Stefan Richter
>
> Currently, the resources such as taken snapshots or iterators are not always
> cleaned up in the RocksDB state backend. In particular, not starting the
> runnable future will leave taken snapshots unreleased.
> We should improve the releases of all resources allocated through the RocksDB
> JNI bridge.
