We will investigate the cost of adding a temporary DSS for now. The DDLs will fill this DSS. This is to develop the DDL side of the database authoritative project without worrying about the end-to-end workflow of the whole feature set that includes CRUD, upgrade/downgrade, etc.

The oplog 'c' entries will be used to fill in the temporary DSS for the create database, move primary and drop database DDLs.
