'placement-infra_hosts' is missing from the example user config

[Jules Dorison]

I tried to install an Openstack Train infrastructure for tests with openstack-ansible (20.0.0).

At the third step, the registration of nova-compute service didn't worked.
After some searches, I found that the nova conductor service was reloading infinitely because it didn't find the placement service in keystone.

In fact the placement service wasn't set up in any of my hosts.

I think since the Train version, the placement hosts must be declared in the 'openstack_user_config' file. Or perhaps am I missing something ?

- [X] This doc is inaccurate in this way:

If this declaration is mandatory, the doc have to be updated to add a "placement-infra_hosts:" group in the example file.

- [X] I have a fix to the document that I can paste below including example:

[...]

# cinder api services
storage-infra_hosts:
  infra1:
    ip: 172.29.236.11

# placement
placement-infra_hosts:
  infra1:
    ip: 172.29.236.11

# glance
image_hosts:
  infra1:
    ip: 172.29.236.11

# nova api, conductor, etc services
compute-infra_hosts:
  infra1:
    ip: 172.29.236.11

[...]

Hi,

We've placed a fix to the docs for the master version, but missed to backport it. So https://review.opendev.org/719428 should resolve this issue.
