[FLINK-2638] [core] Add @SafeVarargs to the ExecutionEnvironment's
"fromElements(...)" method
This helps to get rid of the "unchecked" warnings in places where the
methods are called.
The annotation states that the code can handle false generic types (added
raw or through unchecked casting) without "polluting the heap", i.e. operating
under false assumptions about generic parameters.
I think we can add the annotation here.
