TAJO-882: CLI hangs when a error occurs in the GlobalPlanner.

I added a ErrorInjectionRewriter which throws NullPointerException.
You can inject a error status using the following code.
```
try {
  // Inject in LogicalPlanner
  //testingCluster.setAllTajoDaemonConfValue(("tajo.plan.rewriter.classes",
  //      ErrorInjectionRewriter.class.getCanonicalName());
  
  //  Inject in PhysicalPlanner
  testingCluster.setAllWorkersConfValue("tajo.plan.rewriter.classes",
        ErrorInjectionRewriter.class.getCanonicalName());
} finally {
  // testingCluster.setAllTajoDaemonConfValue("tajo.plan.rewriter.classes", "");
  testingCluster.setAllWorkersConfValue("tajo.plan.rewriter.classes", "");
}
```
