Fluentd: Update kernel and auth inputs to use systemd

Browse Source 
This updates the overrides provided for deploying fluentd as a
daemonset to get kernel messages from the journal instead of
/var/log/kern.log directly, and also uses the journal to get
messages associated with logging to auth.log (syslog facility
10). This provides additional metadata and
a cleaner interface for gathering these logs via fluentd
