Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/remove-db-archiving.

Description:

Nobody seems to use db-archiving in practice.  The shadow tables are thus just overhead in DB migration scripts and tests.

We should remove the shadow tables, and the nova manage db archiving command.

However, much of the logic is reusable in the db-purge2 blueprint (except that we'll actually delete the rows rather than dumping them to shadow tables), so we won't implement this blueprint until after the db-purge2 blueprint is done.
