Today we limit the number of shards concurrently closed by the `IndicesClusterStateService`, but this limit is currently a function of the CPU count of the node. On nodes with plentiful CPU but poor IO performance we may want to restrict this limit further. This commit exposes the throttling limit as a setting.
