Advanced Install Mac Address

[ianalexis]

To facilitate the CTs creation i think we could add a mac address option in the Advanced mode in case already have one assigned with the ip i want.
This could be useful on the WireGuard install for example.

Another use case for this is when you want to re-do an LXC from scratch and you already have a static reservation in your router.

IPs, Port Forwarding, Reverse Proxy, etc, etc, etc...

@ianalexis @btehan For an early look at the v4 script

bash -c "$(wget -qLO - https://github.com/tteck/Proxmox/raw/main/ct/ubuntu-v4.sh)"

If you notice that something is missing, please let me know

Looks great to me. I also like the whiptail menus :-)
Thanks!
