Switched implementation of anti affinity to server groups for both direct and heat engine. Direct engine change is backward compatible. Sahara will detect if old logic is used and will use the same logic for cluster scaling. Note, behavior of anti-affinity changed. Now Sahara will create one server group for cluster and will assign all affected instances to it. So, if anti-affinity enabled for datanode (`dn`) and tasktracker (`tt`) Sahara will not assign node with `dn` and node with `tt` to the same compute. Also note, that server group support will be added to heat only in juno-3. So, environment with up-to-date heat is required.
