CPU Utilization does not seem to reflect current high CPU

[Vedamurthy Joshi]

2.10 44 Ubuntu 14.04 Multi-node icehouse setup

On the tor scale setup, contrail-api continued to hog 40% CPU for sometime.
In the contrail UI, it shows the CPU utlization as low in the detailed graph as shown in attachment

The UVE too continued to reflect low CPU util

Vedu,

The CPU share is normalized by number of CPUs in the system.. what's returned is
(cpu_percent/num_cpus).. this gives an indication of it's share of total processing power..
I think a process % on a 32-core machine vs. 8-core machine needs to be looked at differently..

This is how all the processes are sending their CPU info..

Rahul, can you change the label from
"CPU (%)" to "CPU Share (%)"
