      The server supports many database level commands, but in the storage execution layer those mostly devolve to scanning the CollectionCatalog. Keeping the DatabaseHolder in-memory state in sync with the CollectionCatalog is buggy. Today dropDatabase majority commits dropCollection oplog entries, then as a second step writes the dropDatabase oplog entry and clears the in-memory state.

      Perhaps we don't need to write dropDatabase anymore. Sharding does a bunch of writes to clear database level state in its own config, regardless of the dropDatabase oplog entry.
