Implement initial memory reservation and res_req in jobInfoEnt structure

See this idea on ideas.ibm.com

Hello,

We can get initial memory reservation and initial res_req using bhist command but it can take a while.
I have noticed that initial number of reserved CPUs is recorded in 

/sw/platform/lsf/10.1/include/lsf/lsbatch.h

/**
* \brief  submit request structure.
*/
struct submit {
...

  3627     int     numProcessors;  /**<  The initial number of processors
  3628                              * needed by a (parallel) job. The default is 1. */

 

To be consistent, it would be nice to get initial memory reservation and res_req as well.

This will allow us to query this information from LSF Python API for example.

Please, note that reserved memory value is already available in esub using LSB_SUB_MEM_USAGE.

This would make sense to make this value available during the whole life of a job.

Thanks you

Best Regards
