 Notes:
 - Will not overwrite any files in output cert dir
-- Ansible crypto modules do not support signing certs with own CA yet, using `shell` command instead. Should be resolved in Ansible 2.7 using the [ownca provider](https://github.com/ansible/ansible/commit/b61b113fb9e3fcfcb25f4a8aaabad618e3209ce1).
