[pve-devel] [PATCH pve-network v2 12/19] api: fabrics: add common helpers

[Gabriel Goller]

From: Stefan Hanreich <s.hanreich at proxmox.com>

Since the perlmod API for both the openfabric and ospf are the same,
add helpers for all CRUD operations that will be supported by the
openfabric and ospf endpoints, so they can share the same code.

Additionally we define some standard options for common data types
for fabrics, that will be used by the upcoming fabric API modules.
