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. Change-Id: I7c8f2fb8794b6f9cd2531e54a1a9635010f8c97e
