The initial fluentd client implementation predates the introduction of
service_config_settings, and necessitated some invasive changes to
what is now common/serivces.yaml. This commit modifies existing
services to use the service_config_settings based configuration
mechanism supported by more recent versions of the fluentd support in
puppet-tripleo.
