This change introduces a new base test class that mocks out utils.execute() and similar functions and forces an exception if it gets called. If utils.execute() is mocked by the test case then it will work. What this does is prevent un-mocked access to utils.execute() / processutils.execute() and similar subprocess library functions. Inspired by Julian Edwards' patch to ironic-python-agent Change-Id: Ie5bda8f4c65cf4dfb40b91c11b61485c954addde
