ERR in "RPC Consumer" log: OperationalError: (psycopg2.extensions.TransactionRollbackError) deadlock detected

[Anastasia Palkina]

1. Create new environment
2. Choose Neutron, tunnelling segmentation
3. Choose Ceph for images, Ceph RadosGW for objects
4. Choose Sahara, Murano, Ceilometer
5. Add 3 controller, 1 compute, 1 cinder+mongo, 3 ceph, 2 mongo
6. Move Storage network to eth1
7. Move Management network to eth2 and untag it
8. Start deployment
9. Stop deployment during provisioning
10. Wait until nodes become 'Pending addition'
11. Deploy the environment again. It was successful
12. Run OSTF tests. It was successful

But I found error in "RPC Consumer" log. It appeared during redeployment, when primary controller installed openstack.
