> 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
