Disputes concluding against an included candidate should lead to a rollback and blacklist of particular blocks. The blacklisting mechanism is already implemented in Substrate, so we just need to wire that up to the Chain API subsystem.

We should also figure out how subsystems should be notified of the rollback. This will probably require further changes in Substrate so the overseer can receive notifications of blacklisting.
