Add parameter gpumodel=same for multi node-multi gpu parallel jobs.

To allow LSF more efficient scheduling for multi node multi gpu nodes (that require to run on same type of GPU's) parameter gmodel=same is very important. Today we can only define same model for CPU type but not for GPU type:


Our clients are running Multi Node - Multi GPU jobs. For best efficiency, user need to get for his job GPU only of the same model. 

We know that for MPI jobs there is an option to request HOST of the same CPU type ( -R "select[model=same]" or -R same[model]) But the is no option to define something like:

-gpu num=5:gmem=30G:gmodel=same

To be more clear:

We want our job to be submitted to any gpu type that has 30GB+ gpu memory but the job should get all the 5 gpus ONLY of the same type (it could be our V100 or A40 or any other GPU's group.).
