The basic idea here is to replace the release name in the ClusterInfo object with the fine grained version information queried at runtime. This patch also removes the Name field from the cluster spec, which was also runtime determined and was redundant with ClusterInfo relase name. Signed-off-by: Noah Watkins <noahwatkins@gmail.com>
