* add key in ibc store tracking ibc upgrade heights
Add a new Key to the IBC client store to track the IBC Upgrade Height. This allows IBC upgrades to correctly remove old IBC upgrade states
* update abci and tests
* revert key storage after discussion with @AdityaSripal
Revert using a key to track IBC upgrades. By clearing any IBC state using an old plan in ScheduleUpgrade, IBC upgrades do not need to be tracked by IBC. This reduces code complexity and reduces potential for bugs.
* clear IBC states on cancelled upgrades
