[pve-devel] [PATCH manager 01/12] PVE/API2/Hardware: add Mapping.pm

[Dominik Csapak <d.csapak@proxmox.com>]

adds the basic api calls to list/get/create/update/delete device
mappings

these api calls are only per node, so it only affects
the node specific mapping (thought consistency checks are
done for the whole config, e.g if an id exists already on another
node with a different type)
