> currently helix is not removing state model when resource has been dropped.
> 1) in OFFLINE->DROPPED case, the state model remains in OFFLINE state
> in use cases where resources are dynamically added and dropped, this will
> lead to memory leak of state models in OFFLINE state
> 2) in ERROR->DROPPED case, the state model remains in ERROR state
> in addition to leak, it will cause problems when we re-add the same resource
> in current session. the partition is then still in ERROR state and no
> transition will take place
