+++ This bug was initially created as a clone of Bug #2078989 +++

Description of problem:
Some users use `gather_facts: false` in their playbooks, due to performance issues with fact gathering, or other reasons. However, this breaks the metrics role because it requires some sort of facts like `os_family`, `distribution`, etc. to be defined. The role should work if fact gathering is disabled in the playbook.

NOTE: This may require the user to enable fact caching, or simply not use the metrics role if it is not possible to use fact gathering at all.

Ansible by default will always gather facts in playbooks. In order to test, you can use https://docs.ansible.com/ansible/latest/reference_appendices/config.html#default-gathering to disable fact gathering by default.

e.g.

ANSIBLE_GATHERING=explicit ansible-playbook .... tests/tests_name.yml
