Currently, the list of minions is statically specified in master node, and the list of IP addresses of minion nodes is passed to master node through user_data. This approach doesn't work well on scaling. For example, adding a minion node through stack-update will cause an update on user_data, which cause the master node to be replaced. This commit addresses this issue by dynamically register minion node. There are two cases: * Scale out: the new minion nodes will register themselves to the cluster when they are booting. * Scale in: a subset of minion nodes are deleted by Heat, and the master node will discover it and automatically deregister the deleted nodes.
