ade5bfa302 Use ansible_facts to reference facts
By default, Ansible injects a variable for every fact, prefixed with
ansible_. This can result in a large number of variables for each host,
which at scale can incur a performance penalty. Ansible provides a
configuration option [0] that can be set to False to prevent this
injection of facts. In this case, facts should be referenced via
ansible_facts.<fact>.

This change updates all references to Ansible facts within Kolla Ansible
from using individual fact variables to using the items in the
ansible_facts dictionary. This allows users to disable fact variable
injection in their Ansible configuration, which may provide some
performance improvement.

This change disables fact variable injection in the ansible
configuration used in CI, to catch any attempts to use the injected
variables.

b7b45effed Support deploying the Monasca Agent
The Monasca Agent collects metrics and in this change is deployed
across the control plane. These metrics are collected into an OpenStack
project. It supports configuring a small number of plugins, which can
be extended in later commits. It also makes the Monasca Agent credentials
available to other roles, such as the common role to allow forwarding
logs to Monasca.
