[PATCH proxmox-ve-rs v2 7/8] frr: support custom frr configuration lines

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

When merging the frr.conf.local with the frr.conf, some lines cannot be
merged and we need to add custom frr config lines to the rust
configuration. Add the vec of lines and just dump them into the
template.
