[PATCH proxmox-perl-rs v6 06/24] sdn: route maps: add route map list method

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

Exposes a new method that returns a list of all existing route maps.
Used for implementing a new endpoint in PVE that only returns the IDs
of route maps, which is used in the route map selector component.
