Description of problem:
During overcloud deploy command execution, duplicate containers getting launched for horizon and keystone.



Version-Release number of selected component (if applicable):
RHOSP14


How reproducible:
Always reproducible

Steps to Reproduce:
1. Run "openstack overcloud deploy..." command, overcloud stack create completes but deployment fails at ansible step x(1-5)
2. Run "openstack overcloud deploy --config-download-only..." command to just apply ansible configuration
3. The above command creates duplicate horizon and keystone containers with different names(horizon, horizon_<random_string>) trying to listen on the same port. So one horizon container keeps restarting with error "address already in use", while other one is in healthy state.



Actual results:
Openstack overcloud deploy command should create only one container of a given service and on the next cloud update,  if it finds that the container already exists, it should not launch new duplicate container. It should skip container creation part.

Expected results:
openstack overcloud deploy command creating duplicate containers for same service listening on the same port


Additional info:
