This change introduces a new base test class that mocks out utils.execute and forces an exception if it gets called. This has rooted out many tests that were doing this as a side effect of calling other functions, doing things like modprobe and running iscsi on the host's actual machine. The tests are all now appropriately patched in places where this was happening, and the new base class permanently prevents this from accidentally happening again. If you really want to call utils.execute() then you need to re-mock it in your unit test. Change-Id: Idf87d09a9c01a6bfe2767f8becabe65c02983518
