Added To-Do

README.md

+TO-DO :
+1. To find which language is easier to use with libvirt apis(C or python)
+2. To understand how cpu utilization is calculated for a domain
+3. To find out which type of requests can create following situation
+    - Start client in low load mode with a single server vm running
+    - Increase client load so that goes into high load mode(i.e. cpu utilization of server goes
+    above a threshold)
+    - At this point, autoscaling program intervenes and spawns a new server vm
+    - Now client will divide it's requests to both the servers, resulting in both servers going in low load mode
