The Masakari job uses 4 nodes and defaulted to a quite bulky and not really supported config (MariaDB and RMQ on 4 nodes). This change slims it down so that we test only HA of Masakari and hacluster. The other services are deployed single-node. Additionally, simplify the network group (it does not affect any other job, the logic was simply overdone there).
