...               Code update method BMC using REST
...               Update work flow sequence:
...                 - 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.
...                 - Issue poweroff
...                 - Prune archived journal logs

...                 - Apply preserve BMC Network setting
...                 - SCP image to BMC
...                 - Activate the flash image
...                 - Warm Reset BMC to activate code
...                 - Wait for BMC to come online time out 30 minutes
