    Support soft-anti-affinity policy for nodes

    Currently, there is no guarantee to make sure all nodes of one cluster are
    created on different compute hosts. So it would be nice if we can create
    a server group and set it with anti-affinity policy to get a better HA
    for cluster. This patch is proposing to create a server group for master
    and minion nodes with soft-anti-affinity policy by default.
