Fellype Cavalcante c7091fb8e2 Using non-persistent boot in PXE interface

Non-persistent boot device change is not being used in places
where it should be during cleaning and deployment phases,
due to the default behavior of PXE interface forcing a
persistent change when using legacy function
deploy_utils.try_set_boot_device.
For some drivers, e.g. OneView, a persistent change is far more
costly than a non-persistent one, so this fix can bring
performance improvements.
