Adjustable Number of MPS Daemons for GPU Sharing

See this idea on ideas.ibm.com

For now, IBM Spectrum LSF allows automatically instantiating one single MPS Daemon when requested through the '-gpu' directive:
--
-gpu 'mps=yes:[...]'
--

However, it has proved beneficial in several performance benchmarks conducted on different client applications to have more than one single MPS Daemon running concurrently.
In particular, the following two configurations are of particular interest performance-wise:
- 1 MPS Daemon per Socket
- 1 MPS Daemon per GPU Device

It would be very practical to have LSF be able to handle the two configurations above.
We could imagine an evolution to the '-gpu' directive in the following way:
- '-gpu mps=default' -> One MPS Daemon per node
- '-gpu mps=per_socket' -> One MPS Daemon per socket
- '-gpu mps=per_gpu' -> One MPS Daemon per GPU Device
