Description

AMBARI-21358 introduced schema change to allow tracking upgrade between repository versions instead of free text "version" descriptors. Ambari Server upgrade currently fails because of this schema change if there are any previous upgrades. It's not worth trying to fix the data, and the repositories required for the foreign keys may not even be there anymore. So we should remove upgrade, all child data (upgrade_group, upgrade_item, servicecomponent_history), and the reference from clusters.
