Asynchronous out of band steps in a deploy template fails to
execute. This commit fixes that issue. Asynchronous steps can
set 'skip_current_deploy_step' flag to False in
'driver_internal_info' to make sure that upon reboot same step
is re-executed. Also it can set 'deployment_reboot' flag to True
in 'driver_internal_info' to signal that it has rebooted the node.
