v If the map parameter is cluster, the mapping of the host and host type is
changed to be the cluster's mapping and type.
v If the map parameter is host, the mapping of the cluster and its host type is
changed to be the host's mapping and type.
v If the map parameter is clusterWithHostExceptions the host is keeping his
mapping and apply on it the cluster mapping as well
v Use map=host to add a host to an empty cluster. This way to cluster will receive
