Update the server power state dynamically in GUI

This uses websocket mechanism to retrieve the server power state and
update the same.

Resolves openbmc/openbmc#3102

Tested: Running GUI locally and verified the following scenarios:
- Power on operation from GUI and host command line
- Power off operation from host command line
- Warm reboot operation from GUI
- Cold reboot operation from GUI
- Immediate shutdown operation from GUI
- Orderly shutdown operation from GUI
In all of the above scenarios state change is notified to GUI at right time.
