Error running os-nova-install with nova-config tag in 15.0.0

[James Denton]

OS: Ubuntu 16.04 LTS
Release: Ocata 15.0.0

Running "openstack-ansible os-nova-install.yml --tags nova-config" results in the following:

nova_get_venv is registered in /etc/ansible/roles/os_nova/tasks/nova_install.yml, and does not appear to be registered by the time this task is run (if at all when using this tag). Commented out the conditional to work around it.

I get similar error on stable/newton, Ubuntu 14.04 and 16.04 when building AIO:

fatal: [aio1]: FAILED! => {"failed": true, "msg": "The conditional check 'nova_get_venv | failed or nova_developer_mode | bool' failed.

[Jean-Philippe Evrard (jean-philippe-evrard)]

FYI, I don't think we ever ensured that -config tag will "only reconfigure" service (like templating files?)

If that's the case, I think it deserves documentation.

Currently we are focusing on having a reliable -install as first base.
