Bug Description

This came up in the upgrades SIG room at the Stein PTG:

https://etherpad.openstack.org/p/upgrade-sig-ptg-stein

The request is that failing to archive/purge old deleted records from the database can cause upgrades to have major downtime because of the old records (heat and keystone are known major issues here, but clearly also instances records) - and they would like a nova-status upgrade check that checks some configured limit on deleted instances and warns if you should archive/purge prior to starting the upgrade.

The question would be what is a sane default (1000000 soft deleted instances records?), or something based on a time limit (deleted instances over 3 years old), etc.
