Adjust tests to skip the sqlalchemy test if sqlalchemy is not installed. Adjust examples to fallback to a directory based backend if the sqlalchemy does not load or is not available. Include a updated tox.ini (generated from the toxgen.py script) that includes the new venv variations. Change-Id: I7686f09901a9b65d7c81b4e037b5bffc24aa7ef7
