The kolla-genpwd and kolla-mergepwd commands can be used to manipulate
the kolla passwords.yml file. The format is a YAML encoded dict of
password variable names to their values. If the format is not a dict,
the error messages are unhelpful. In particular, this can happen if the
file is encrypted e.g. via Ansible Vault.
For kolla-genpwd:
AttributeError: 'NoneType' object has no attribute 'items'
For kolla-mergepwd:
AttributeError: 'NoneType' object has no attribute 'update'
This change adds a more friendly message.
