Steps to reproduce:
Execute 'network_config_consistency_on_reboot' test with:
1. Revert snapshot with 5 slaves
2. Create cluster (HA) with Neutron VLAN
3. Add 3 controller and 1 compute + cinder nodes
4. Upload 'default_ovs' network template
5. Create custom network groups basing on template endpoints assignments
6. Run network verification
7. Deploy cluster and run basic health checks
8. Run network verification
9. Check L3 network configuration on slaves
10. Check that services are listening on their networks only
11. Reboot a node << Failed here
12. Run network verification
13. Check L3 network configuration on slaves
14. Check that services are listening on their networks only
15. Run OSTF

Expected results:
