Description of Drivers Ticket:

SERVER-35804 has made it invalid to drop collections on the admin database in a sharded cluster, which has caused FLE tests to fail with duplicate key errors on the "latest" server variant due to step 2 in https://github.com/mongodb/specifications/tree/master/source/client-side-encryption/tests#use-as-integration-tests

Maybe we can get around this by doing a deleteMany({}) instead of a drop?
