Comment 1 for bug 1712436

I've been hitting this issue in newton jobs to gate rdoinfo reviews in RDO. I've been digging a bit on it and these are my findings:

- The problem in newton jobs seems to be that CONTROLLER_HOSTS variable is not being passed when calling deployed-server/scripts/get-occ-config.sh from tht [1], so it's not enabling os-collect-config service.

- Last time the job passed, it passed this variable to the script [2]

- In ocata, it's not passing the variable [3] but it's catching it via Controller_hosts variable as get-occ-config.sh has some code in ocata not present in newton [4]

- In master, we have the same as in ocata [5]

I'm not sure what changed it, could someone more familiar to tripleo-ci scripts take a look?
