I think its sufficient to have the configuration parameter in the
`CheckpointConfig`, without any convenience methods in the
`StreamExecutionEnvironment`.
The `StreamExecutionEnvironment` is getting hard to maintain with those
changes.

> FLINK-3051 introduced already a filed in the {{CheckpointConfig}} to specify
> a min pause between checkpoints.
> In high-load situations (big state), jobs might spend their entire time
> creating snapshots, not processing data. With a min pause between
> checkpoints, users can guarantee that there is a certain time-span the system
> can use for doing some actual data processing.
