Description of problem:

I deployed rhos 11 with octavia(1 controller 2 compute nodes) - 
Ran post deployment scrip -
https://review.openstack.org/#/c/447496/11/doc/source/advanced_deployment/octavia-post-deploy.sh

on the controller: 
in /etc/octavia/octavia.conf I uncommented "bind_host" and configured it with controller ip instead of localhost address. 

In /etc/octavia/conf.d/common/octavia-post-deploy.conf I commented out the "bind_host". 

After restarting the services I saw the following for health manager service- 

[root@controller-0 ~]# systemctl status octavia-he* -l
