[PATCH pve-manager 4/5] fabrics: wireguard: add mtu to interface properties

[Stefan Hanreich <s.hanreich@proxmox.com>]

The minimum value of 576 is based on the minimum datagram size a node
must be able to handle, as according to RFC 791. In practice, MTU
values should be significantly higher anyway. Make 1420 a soft-default
by prefilling the MTU field. This allows for making it the de-facto
default without breaking the current behavior of the API.
