Users instantiating the QEMUMachine class will be able to set the location of the directory that will *contain* the QEMUMachine unique temporary directory, so that parameter name has been changed from test_dir to base_temp_dir. A property has been added to allow users to access it without using private attributes, and with that, the directory is created on first use of the property.
