> we see that when DROPPED state is not in the StateModelDefinition, partition will fail
to be dropped. this causes problem when we are using auto_rebalance mode, because we are dropping
mappings and assign new mappings to nodes. things need to verify:
> 1) state transitions are all valid, no self loop/loop, no unreachable state
> 2) state meta is valid
> 3) drop state included
