Ansible fact namespacing
------------------------
Ansible facts, which have historically been written to names like ``ansible_*``
in the main facts namespace, have been placed in their own new namespace,
``ansible_facts.*`` For example, the fact ``ansible_distribution`` is now best
queried through the variable structure ``ansible_facts.distribution``.
A new configuration variable, ``inject_facts_as_vars``, has been added to
ansible.cfg. Its default setting, 'True', keeps the 2.4 behavior of facts
variables being set in the old ``ansible_*`` locations (while also writing them
to the new namespace). This variable is expected to be set to 'False' in a
future release. When ``inject_facts_as_vars`` is set to False, you must
refer to ansible_facts through the new ``ansible_facts.*`` namespace.
