  [DEPRECATION WARNING]: The TRANSFORM_INVALID_GROUP_CHARS settings is set to allow bad characters
  in group names by default, this will change, but still be user configurable on deprecation. This
  feature will be removed in version 2.10. Deprecation warnings can be disabled by setting
  deprecation_warnings=False in ansible.cfg.
   [WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see
