I copied it from a different project and I didn't check if it's needed
at all.

host01 is choking from everything I run on it. ns4 has encrypted volumes
and is secure enough for the logs (I don't think there are passwords or
keys in the logs, just some private information).

Pretend it's filebeat, so the logs in Kibana are unified.

This reverts commit c5571243.

I changed my mind, I'll setup just journalbeat to use the filebeat
indices.
