Description of problem:

Hi,

When working on https://bugzilla.redhat.com/show_bug.cgi?id=1751709, we noticed that tripleo had spawned 2 distinct containers for nova_compute on several compute nodes:

cmpc01 docker_ps logs [1] shows 3 x container instances for nova-compute, and the images are from:
    10.30.182.10:8787/rhosp13/openstack-nova-compute-multipath:rev1

cmpc04 docker_ps logs [2] shows 2 x container instances for nova-compute, and the images are from:
    registry.access.redhat.com/rhosp13/openstack-nova-compute:13.0-XX
    
The questions is why the repositories changes and why in [1] we saw computes with 2 nova_compute container.
