[PATCH cluster v2 6/6] datacenter config: add unique-next-id to schema

[Severen Redwood]

Add the `unique-next-id` property to the datacentre config schema to
track whether only unique (ie. neither currently nor previously in use)
VM/CT IDs should be suggested by the `/cluster/nextid` API endpoint.
