Shutdown metadata is keyed on node id. This makes sense since only one
node with a given node id can exist within a cluster. However, it is
possible that shutdown was initiated for one instance of a node, but
that node is restarted. This commit adds the ephemeral node id to
shutdown metadata so that nodes with the same id but different ephemeral
id can be distinguished.
