Synopsis: Modifications to handle Cray specific default job parametersassign value to 'vntype' attribute of a job, when platform is Cray.
Details:
- Introduction of new attribute called "Aprun_parameter" which user can specify through job attributes during job submission.
- If platform is an actual Cray cluster or Cray ALPS simulator then perform below:
- If "Aprun_parameter" set, then assign "Aprun_parameter" value to "Aprun_param", else assign default value as "-B sleep 100" to "Aprun_param".
- If "Resource_List.select" not present in job attributes passed by the user, then assign default value as "1:ncpus=1:vntype=cray_compute" to "Resource_List.select".
- If vntype specified and value is "cray_compute" then call Job.cray_script() passing "Aprun_param" as a parameter to it, else run default sleep 100.

- :
- Set vntype value as 'cray_compute'.

Synopsis: New method to create default Cray job script using aprun which accepts aprun parameters
Details:
...
consider aprun command if the platform is Cray.
Details:
- If platform is an actual Cray cluster or Cray ALPS simulator:
- Prefix job executable with "aprun -B".
- If user is creating job script using 'create_script' inside test case then do not prefix "aprun -B", also user will have a full control over a job script same as how existing PTL works.
- Assign requested users home directory path to 'submit_dir'.
