examples:power add command line args to guest app

Add new command line arguments to the guest app to make testing and validation of the policy usage easier. These arguments are mainly around setting up the power management policy that is sent from the guest vm to to the vm_power_manager in the host

New command line parameters:
-n or --vm-name
sets the name of the vm to be used by the host OS.
-b or --busy-hours
sets the list of hours that are predicted to be busy
-q or --quiet-hours
sets the list of hours that are predicted to be quiet
-l or --vcpu-list
sets the list of vcpus to monitor
-p or --port-list
sets the list of posts to monitor when using a workload policy.
-o or --policy
sets the default policy type
TIME
WORKLOAD
TRAFFIC
BRANCH_RATIO

The format of the hours or list paramers is a comma-separated list of integers, which can take the form of
a. x e.g. --vcpu-list=1
b. x,y e.g. --quiet-hours=3,4
c. x-y e.g. --busy-hours=9-12
d. combination of above (e.g. --busy-hours=4,5-7,9)
