[PATCH proxmox-ve-rs 3/9] ve-config: add redistribute setting to ospf section config

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

The settings are global to the fabric, which means that every node
participating in the fabric will have the same redistribution
settings. For now this seems sufficient, but if the need arises it is
always possible to implement a node-level override.
