Review comment:
I think that's a great idea. We can start thinking about that on the
mailing list and handle this via separate JIRA issue. This pipeline option can
then be replaced by the generic configuration option.
For now, this pipeline option will fulfill a common request by Beam users to
directly set the state backend without having to change the Flink configuration.

> We should make it easier to configure a Flink state backend. At the moment,
> users have to either (1) configure the default state backend in their Flink
> cluster, or make sure (2a) they include the dependency in their Gradle/Maven
> project (e.g.
> {{"org.apache.flink:flink-statebackend-rocksdb_2.11:$flink_version"}} for
> RocksDB) (2b) set the state backend factory in the {{FlinkPipelineOptions}.
> The drawback of option (2) is that it only works in Java due to the factory
> specification being in Java.
> We can make it easier by simple adding pipeline options for the state backend
> name and the checkpoint directory which will be enough for configuring the
> state backend. We can add the RocksDB state backend as a default dependency.
