      Summary

      Add SDAM tests to ensure the TopologyType remains "Single" when a standalone node is restarted as a replica set or mongos.

      The SDAM spec says:

      The TopologyDescription's type was initialized as Single and remains Single forever. There is always one ServerDescription in TopologyDescription.servers.

      PyMongo supports online change from standalone to replica set and standalone to sharded. The tests added in this change would confirm that behavior in all drivers.
