"""
HTTP POST "/" 

Once receive the POST request, your server program should create a 
separate process for running "stress_cpu.py" (attached below). 
"stress_cpu.py" runs an intensive computation loop to stress the
CPUs to 100% utilization. This script is for triggering the auto 
scaling policy that you will setup later. 

In Python, use subprocess.Popen() to create a separate process so 
that your HTTP server is non-blocking. That is to say, after 
receiving a POST request for stressing the CPU on your EC2 
instance, your server program should still be able to handle 
further POST/GET requests.

HTTP GET "/"

Your server program should return the private IP address of the 
EC2 instance. In Python, you can import socket and use 
socket.gethostname() to get the IP address.
