[PATCH pve-manager v3 23/26] ui: fabrics: wireguard: add node edit panel

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

Add a component for creating / updating nodes of a Wireguard fabric.
There are some key differences compared to OSPF / OpenFabric nodes,
mostly that WireGuard nodes can have different roles and that
WireGuard interfaces are not selected from the existing interfaces of
the node, but rather created. This requires some changes to the
existing NodeEdit panel provided by the fabrics:

* do not load available interfaces, but rather available peers
* let users create interfaces rather than select them
* add an additional roleSelector to the existing nodeSelector
