supress output of bsub on import

[winnubstj]

I get this message whenever I import ClusterWrap.

Unknown option: V
Usage:
bsub [-cwd Working Directory Path] [-e Error Path] [-I Interactive Mode]
[-m Node List] [-M Memory Limit] [-n Min Process] [-o Output Path] [-q
Queue Name] [-W Time] [-x Exclusive] [-h] [script]

This suppresses the terminal output and handles this exit code scenario.
