Comment 16 for bug 1611704

Update on the progress:
> 1. Figure out ordering issues so the rabbit password can be changed on update
https://review.openstack.org/#/c/402061/ - In discussion

> 2. Output a password environment file in addition to the generated tripleo-overcloud-passwords file - the data contained will be the same, but the format will be directly consumable via heat similar to my example above.
https://review.openstack.org/#/c/427044/ - In progress

> 3. Have the option to disable internal generation of random passwords, so the deployment will fail if an operator provided password file doesn't contain a password for a new service.
