QEmu Guest Agent - Disable log messages for ping

Goal

In the QEmu Guest Agent, disable/remove or make it configurable to log a message if the QEmu Guest Agent gets pinged (info: guest-ping called).

Technical details

Either remove this logging entirely or make it configurable.

Additional information

Background information: I am using Proxmox as a hypervisor and if someone navigates to a vm or lxc overview the QEmu Guest Agent is constantly pinged. This is not a big problem since this happens only if you are viewing the summery page of this VM/LXC. I started to use pulse (https://github.com/rcourtman/pulse) to monitor my proxmox setup. This tool calls the proxmox api and the proxmox api pings EACH guest every 10 seconds. This leads to an journal/syslog/eventlog entry every 10 seconds on every VM. Which generates a noticeable, unnecessary load to the System and also to the disks, since the log is written by each VM/LXC.
