dcos-check cockraoch checks also dead/decommissioned nodes.

[azzeddinefaik]

I am doing upgrade of dcos nodes and todo this successfully, I need to replace nodes. I keep same IPs. When I deployed first master node all went well. but when I tryed second node. I see Master Node Poststart Checks failing due to 'underreplicated ranges' error.

When I checked Cockroachdb :

I check zone configuration looks : replica factor is 5.
when I checked, I saw that the dcos-check used 127.0.0.1:8090/_status/nodes to get stats about nodes. but it include dead nodes. in my case one of dead/decommissioned node have under-replicated range ( node 1 - 62 ) but as I am using same IP as node 7. I can not recommission it.

can you help to re-mediate the situation.
Thanks a lot!
