It is executed in WikipediaEditsSourceTest. In the latest commit, this module still depends on flink-streaming-java, and also flink-clients of test scope.

> Key: FLINK-7065
> URL: https://issues.apache.org/jira/browse/FLINK-7065
> Project: Flink
> Issue Type: Improvement
> Components: DataStream API
> Reporter: Xu Pingyong
> Assignee: Xu Pingyong
>
> Motivation:
> It is not good that "flink-streaming-java" module depends on "flink-clients". Flink-clients should see something in "flink-streaming-java".
> Related Change:
> 1. LocalStreamEnvironment and RemoteStreamEnvironment can also execute a job by the executors(LocalExecutor and RemoteExecutor). Introduce StreamGraphExecutor which executors a streamGraph as PlanExecutor executors the plan. StreamGraphExecutor and PlanExecutor all extend Executor.
> 2. Introduce StreamExecutionEnvironmentFactory which works similarly to ContextEnvironmentFactory in flink-clients.
> When a object of ContextEnvironmentFactory, OptimizerPlanEnvironmentFactory or PreviewPlanEnvironmentFactory is set into ExecutionEnvironment(by calling initializeContextEnvironment)， the relevant StreamEnvFactory is alsot set into StreamExecutionEnvironment. It is similar when calling unsetContext.
