VMware: Remove unnecessary deepcopy()s in test_configdrive
VMware: Remove unnecessary deepcopy()s in test_configdrive

test_configdrive was doing a deepcopy of its test_instance object in
some tests. This was unnecessary, as the object is created fresh in
setUp().

Also, change a couple of dict lookups of test_instance to object
properties.
