-----------------------------------

             Summary: Add metric showing how many nodes may safely leave the cluster wihout partition loss
                 Key: IGNITE-12278
                 URL: https://issues.apache.org/jira/browse/IGNITE-12278
             Project: Ignite
          Issue Type: Improvement
            Reporter: Ivan Rakov
             Fix For: 2.8


We already have getMinimumNumberOfPartitionCopies metrics that shows partitions redundancy number for a specific cache group.
It would be handy if user has single aggregated metric for all cache groups showing how many nodes may leave the cluster without partition loss in any cache.
