Description anil venkata 2020-04-08 16:25:51 UTC 
Description of problem:

After running the rally scenario (which ran successfully), some stale "neutron-metadata-agent-ovn" containers exist on compute nodes (though all neutron resources are deleted successfully by rally).

Note: This rally scenario boots 1000 VMs and and pings their floating ip.

OSP version: OSP16
Puddle: RHOS_TRUNK-16.0-RHEL-8-20200226.n.1
Number of controller nodes: 3
Number of compute nodes: 3
