[PATCH manager v6 16/18] fix #4369: ui: dc options: add option for unique VM/CT IDs

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

From: Severen Redwood <severen.redwood@sitehost.co.nz>

Add an additional checkbox to the "Next Free Guest ID" option that
allows choosing whether the `/cluster/nextid` API endpoint (and thereby
any UI elements that suggest IDs) should avoid suggesting previously
used IDs. This option defaults to off to ensure that this change in
behaviour is opt in.

Also rename the top-level option to "Next Free Guest ID" since it's no
longer just the range.
