[PATCH cluster v8 03/22] datacenter config: next-id: add enforce subproperty

["Michael Köppl" <m.koeppl@proxmox.com>]

Add 'enforce' as a subproperty to the next-id config schema. If enabled,
guest IDs outside of the configured range are rejected and, if 'unique'
is enabled as well, previously used IDs are also rejected, even if they
are not currently in use. The boundaries of the range count only when
explicitly configured, not for defaults.
