We are purging all downgrade methods from icehouse to havana because:
1) havana is going to become unsupported during Kilo cycle.
2) most people will upgrade from icehouse, while a minor percentage
from havana
3) downgrade use cases are mostly to revert after failed upgrades
See discussion in https://review.openstack.org/109952 for details.
This change removes all downgrade code in this migrations and raises
an exception in downgrade of icehouse_release.
Partially-implements: blueprint reorganize-migrations
