[PATCH pve-manager 1/3] api: add mappings to resources endpoint

[Jonas Theisen <j.theisen@proxmox.com>]

Similar to the SDN zones this patch adds the USB, PCI and
directory mappings to the resources endpoint of the API.
It adds a new type 'mapping' for this and distinguishes
the mappings with 'mapping-type' in the returned object.

This is needed to allow the permissions tab to gather
the IDs of the mappings for the paths list.
