Comment 5 for bug 1573502

Reproduced again on iso #481

Scenario:

https://product-ci.infra.mirantis.net/view/9.0_swarm/job/9.0.system_test.ubuntu.plugins.thread_keystone_separate_services/142/console

I seems, that nodes with two custome roles have only one corosync_role
Here is the difference:

[root@nailgun ~]# fuel node | grep keystone
8 | ready | slave-09_standalone-keystone | 1 | 10.109.5.11 | 64:a8:3b:9e:ee:dd | standalone-keystone | | 1 | 1
5 | ready | slave-05_standalone-database_standalone-keystone | 1 | 10.109.5.7 | 64:b6:b1:ba:a1:7a | standalone-database, standalone-keystone | | 1 | 1
3 | ready | slave-04_standalone-database_standalone-keystone | 1 | 10.109.5.6 | 64:a9:c0:f6:29:17 | standalone-database, standalone-keystone | | 1 | 1
7 | ready | slave-06_standalone-database_standalone-keystone | 1 | 10.109.5.8 | 64:b0:b6:69:6f:26 | standalone-database, standalone-keystone | | 1 | 1
[root@nailgun ~]# for id in 3 5 7 8; do ssh node-$id hiera corosync_roles; done
