Cinder DB Archiving
In Nova (Grizzly) we added new feature DB Archiving.
The problem:
We actually don't delete rows from db, we mark it only as deleted (we have special column).
So the DB is growing and growing, so this causes problem with performance.
The solution:
Create shadow tables and copy "deleted" rows from main to shadow table.
Steps to implement:
1) sync utils for work with shadow table (create, check methods)
2) add db migration, that will create all shadow tables
3) write tests for shadowing (for example checking that all shadow tables are up-to-date)
4) add utils to work with shadowing (periodic task, manager method)

(smcginnis): Marking obsolete as this has been sitting out there for a long time. If this is still needed, please submit a new bp.
2015-07-24 <thingee>: Per Ivan, removing this from Liberty since this needs to be rethought cross project.
We should rethink current db-archiving strategy so this work will be done only in Ice House --boris-42
