Remove/destroy DTR replica 

I think the actual documentation can be confusing.
In fact if we want to completely remove a DTR cluster, we can use the destroy command, it is fine.

But, if we just want to remove a replica from a cluster, it is better to use the remove command which is safer and cleaner.
The destroy command do not send a notification to the RethinkDB on the others replicas which can be dangerous and leads to unhealthy DTR clusters.
