   > * What about open or closing containers, that is, containers that should 
be closed before decommission progresses? The RM report currently does not have 
fields for these, so we will have to add them.
   
   I was thinking that decommission monitor should not bother calling RM for 
OPEN or CLOSING containers - it can easily see it has to wait on them already 
itself. I should just make a call for containers it needs to check the 
replication status of.
   
   > * The general idea is that some handler in the chain will return `true` 
before a handler that decommission cares about can check the container. For 
example, `QuasiClosedContainerHandler` return true to close a container that is 
also missing a replica.
   
   One thing we can do, is use the return value of "handled" which is true if 
some handler took action on the container or false if it passed through 
cleanly. But we need to think if there are any edge cases there too ...
