Add/modify GPU affinity options for LSF

The objective is to add to and modify the GPU affinity options that LSF makes available via bsub -gpu, as follows.

1. When a user requests NVIDIA MPS via a LSF bsub -gpu option, the default GPU affinity should be "off", meaning that LSF should set no CUDA_VISIBLE_DEVICES variables in the user's execution environment ... as recommended in NVIDIA's MPS documentation.

2. If a user requests GPU affinity via a LSF bsub -gpu option, I would really prefer to see affinity options "block | cyclic | off", instead of the current "yes | no"; where "block" means the first N ranks are assigned GPU 0, the next N ranks are assigned GPU 1, etc.; "cyclic" means cyclic over the GPUs that are socket-local, and "off" means that LSF is not setting any CUDA_VISIBLE_DEVICES variables in the user's execution environment.
