cpupower : Auto-completion for cpupower tool 



This script adds support for auto-completion for cpupower tool.
Added support for auto-completion of all the eight commands for
cpupower tool and their all subsequent sub-commands, wherever
possible.

A sample output after applying this script -

root@ubuntu:~# cpupower f<TAB>
root@ubuntu:~# cpupower frequency-<TAB>
frequency-info  frequency-set
root@ubuntu:~# cpupower frequency-set -
-d          --freq      --governor  --min       --related
-f          -g          --max       -r          -u
