> After HDDS-1138, the OM client will not talk to SCM directly to fetch the pipeline info.
Instead the pipeline info is returned as part of the keyLocation cached by OM. 
>  
> In case SCM pipeline is changed such as closed, the client may get invalid pipeline exception.
In this case, the client need to getKeyLocation with OmKeyArgs#refreshPipeline = true to
force OM update its pipeline cache for this key. 
>  
> An optimization could be queue a background task to update all the keyLocations that
is affected when OM does a refreshPipeline. (This part can be done in 0.5)
