[PATCH proxmox-perl-rs 2/2] sdn: add method to get a frr template

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

The templates are now stored inside of the proxmox-frr binary because we
use `include_str!`. In pve-network we need to use these templates to
check if they have changed and compare them to the override templates
(in the postinst). We also need the templates for the pvesdn cli so that
the user can create overrides.
