Log message:
Import beats 5.1.1 as sysutils/beats (based on wip/beats).

The Beats are lightweight processes, written in Go, that you install
on your servers to capture all sorts of operational data like logs,
operating system metrics or network packet data, and to send it to
Elasticsearch, either directly or via Logstash, so it can be
visualized with Kibana.
