Deletes the store house specified in the connection descriptor. If this data source doesn't use a store house, this method should be a no-op. If this data source DOES use store houses, but support for dropping them is not implemented yet, this should throw a NotImplementedException. Store house typically corresponds to "database". If there is no store house with the given name, this should be a no-op. For SQLite, this just deletes the database file.
