Allow archiving deleted rows to shadow tables, for performance.
Implements bp db-archiving
Add versions of all tables with "shadow_" prepended to their names.
These shadow tables do not have indexes.
Adds API function archive_deleted_rows, which moves some deleted
rows from production tables to the corresponding shadow tables.
(It only does a few rows, to avoid blocking the process or hitting
the database too hard. So it needs to be called regularly.)
Also adds a db archive_deleted_rows command to nova-manage.
Uses Boris Pavlovic's code for copying columns from existing tables
to new tables.
