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 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.
