There's a usecase, where all datasets might be the same, except setup_hosts. For example, when we use isolated rabbitmq cluster for RPC but shared one for notifications. And we have same set of users and vhosts there. In current state setup won't be performed, since vhosts and users are the same. Change-Id: Ib5c44327d5f1edc25bace79fdd057adabb0b4c14
