Remove extraneous failed server/image tests

These test cases required fixture abuse that no longer works in
fixtures 1.3.0. They also had nothing to do with the glance and nova
utils, but instead tested rally.benchmark.utils.get_from_manager(),
which has its own tests in tests.benchmark.test_utils.py.
