[FLINK-1008] Fix createProgramPlan() throws exception
Problem was, that ExecutionEnvironment#getExecutionPlan clears the data
sinks, i.e. a following ExecutionEnvironment#execute will throw an error
because there are no data sinks.
This introduces a new flag for ExecutionEnvironment#createProgramPlan to
indicate, that the the sinks shall not be cleared.
This does not break any existing code.

> After calling createProgramPlan() I get the following exception:
> java.lang.RuntimeException: No data sinks have been created yet. A program
> needs at least one sink that consumes data. Examples are writing the data set
> or printing it.
> at
> eu.stratosphere.api.java.ExecutionEnvironment.createProgramPlan(ExecutionEnvironment.java:618)
> at
> eu.stratosphere.api.java.LocalEnvironment.execute(LocalEnvironment.java:51)
> at
> eu.stratosphere.api.java.ExecutionEnvironment.execute(ExecutionEnvironment.java:516)
> The plan execute and we also have data sinks, so the error is really
> confusing.
