Read_cpuutil

Program to read CPU utilization

Task here is to compute CPU utilization using mpstat or systat framework.

Completed:

• Added makefile to build project.
• Added cpu_util.h containing API to call get_cpu_util_perc to get CPUUTIL in %.

ToDo:

• Add the master-slave model to call and set frequency using CPU UTIL from the slaves.
• Bind each slave to it's cpus/cores.
• Define model or topology between each slaves.
