[contrail] after deletion controller node redeploy fails

[Denis Deryabin]

Test scenario:

"Verify that Controller node can be deleted and added after deploying"
1 Create an environment with "Neutron with tunneling segmentation" as a network configuration
2 Enable and configure Contrail plugin
3 Add some controller (at least 3), compute and storage nodes
4 Add 3 nodes with "contrail-db", "contarail-config" and "contrail-control" roles on all nodes
5 Deploy cluster
6 Run OSTF tests
7 Delete a Controller node and deploy changes
8 Run OSTF tests
9 Add a node with "Controller" role and deploy changes
10 Run OSTF tests
11 Expected results: All steps must be completed successfully, without any errors.

Actual result:
Redeploy fails on step 7 with message:

>Deployment has failed. Method granular_deploy. Deployment failed on nodes 1.
