From now on only rely on the IPA inventory and 2 additional fields: boot_interface and root_device. Also updated unit tests to use one inventory example. Also removed duplicating unit tests and checks in test_process. Also removed devstack support for the old ramdisk. Change-Id: Ib382328295fc2c1b9143171b1047304febadcaca
