FInalise WireGuard Update on Proxy Instance

[jacderida]

The output from the last update contained this:

DKMS: install completed.
You appear to have just upgraded WireGuard from version v0.0.20190406 to v0.0.20190601.
However, the old version is still running on your system. In order to use the
new version, you will need to remove the old module and load the new one.
You can accomplish this with the following commands:

    # sudo rmmod wireguard
    # sudo modprobe wireguard

So the proxy will need to be restarted. We should probably be quite careful and confirm this in staging first.
