Alexander Gordeev f00be1a3a6 Use another execute wrapper + tiny fixes
* Ditch oslo's `execute` wrapper from utils.py;
* Fix first partition beginning;
* Use proper arguments order for `mdadm`;
* Fix unicode string handling for fs_utils;
* Add sleep to execute;
* Fix nailgun image data fields;

Partially implements: blueprint image-based-provisioning
