[FLINK-19135] Strip ExecutionException in (Stream)ExecutionEnvironment.execute()
In FLINK-14850 we changed the execute() method to be basically
final JobClient jobClient = executeAsync(...);
return jobClient.getJobExecutionResult(userClassloader).get();
Unfortunately, this means that execute() now throws an
ExecutionException instead of a ProgramInvocationException or
JobExecutionException as before. The ExecutionException is wrapping the
other exceptions that we were throwing before.
We didn't notice this in tests because most tests use
Test(Stream)Environment which overrides the execute() method and so
doesn't go through the PipelineExecutor logic or the normal code path of
delegating to executeAsync().
This change brings us back to the previous behaviour.
