This makes the default database name for cell0 be based on the main database name, not the api one. Before this, we would get a database name of nova_api_cell0 by default, intead of nova_cell0. This was confusing because cell0 has "main" schema inside, not "api" schema. Closes-Bug: #1656673 Change-Id: I86797785f76c2c927a4db8fef72b8f8d986af6b9
