[PATCH proxmox-ve-rs 6/9] frr: add isis configuration and templates

[Gabriel Goller <g.goller@proxmox.com>]

Add templates and rust configuration types to render configuration for
the isis daemon. This allows us to generate the config in perl, then
pass it to rust and then render the template in rust.
