Original description: Before this Command Monitoring Tests we need to drop a database, and recreate a collection. Conversations with esha.maharishi have revealed that drivers must explicitly run flushRouterConfig against connected mongos when we drop databases. jeff.yemin suggests we run against a single mongos (modifying the URI that mongo orchestration provides us to only use a single address), but Esha points out that this just happens work because of an optimization in the mongos that dropDatabase is called on.
