Wireguard Observium Agent

Hello,

please add wireguard support simliar to the openvpn agent script to get a vpn connected graph.

To get a list with the current connected clients use the command:

wg show all dump | awk 'BEGIN {}; {if (systime()$6 < 300 ) print strftime("%m%d-%Y %H:%M:%S", systime()),$5, $4, (systime()-$6) "sec" } ; END {}'

See: https://manpages.debian.org/unstable/wireguard-tools/wg.8.en.html#show
