[Vladimir Khlyunev]

Several swarm threads failed (all detach-plugins):
https://product-ci.infra.mirantis.net/job/9.0.system_test.ubuntu.plugins.thread_db_separate_services/81/testReport/(root)/separate_db_service/
https://product-ci.infra.mirantis.net/job/9.0.system_test.ubuntu.plugins.thread_2_separate_services/81/testReport/(root)/separate_rabbit_service/

Steps to reproduce:
0. Build & install detach-db/rabbitmq/keystone plugin
1. Create cluster
2. Add 3 nodes with controller role
3. Add 3 nodes with rabbit role
4. Add 1 compute and cinder
5. Verify networks
6. Deploy the cluster

Expected result:
No errors, cluster is deployed and operational

Actual result:
Deployment failed, error from logs:
err: The node role is not in corosync roles at /etc/puppet/modules/osnailyfacter/manifests/cluster/cluster.pp:6 on node node-4.test.domain.local
