...                 - User input BMC File existence check
...                 - Ping Test and REST authentication
...                 - Set Host Power host setting Policy to RESTORE_LAST_STATE
...                   On reboot this policy would ensure the BMC comes
...                   online and stays at HOST_POWERED_OFF state.
