Restart filebeat when rotating HAProxy logs

The current contents of /etc/logrotate.d/haproxy are:

    /var/log/haproxy.log {
        daily
        rotate 5
        missingok
        notifempty
        compress
        postrotate
            /usr/lib/rsyslog/rsyslog-rotate
        endscript
    }

So most of this is translating from the existing logrotate config to
expressing that as a puppet resource. But also, I'm adding a filebeat
restart because filebeat is holding files open and filling up disks.
