We should allow Tendermint clients to accept proof of a particular key in state mapped to a new chain ID & height as sufficient reason to change their chain ID & height.

This can then be used to allow non-contentious upgrades which change chain ID and/or height.

The mechanism used to deal with chain-id changes should also allow for changes to UnbondingPeriod, and ConsensusParams as described here: #6516
