CommandLine: cmd build order issue

[ZDu-IDM]

Not consistent with COMPSPlatform

# COMPS: idmtools_platform_comps/idmtools_platform_comps/comps_operations/simulation_operations.py
sim_task = command.arguments + " " + command.options
sim_task = sim_task.strip()
print("executable: ", command.executable)
print("COMPS Command: ", sim_task)

Also in singularity case, with command.add_option is called, final cmd may not be right (put parameter in between singularity and exec sif_file.
