[PATCH SERIES v3] Add ability to prevent suggesting previously used VM/CT IDs

[Severen Redwood]

Hi everyone,

This is a small update to my previous patch series [1, 2]
adding optional support for preventing PVE from suggesting
previously used VM/CT IDs.

In particular, missing use statements have been added to the
patches for marking VM/CT IDs as used, as noticed by Aaron
[3]. Everything else remains the same as in v2.

Also note when building this patch series that the pve-cluster
patches must be applied and built first to prevent the build
of pve-manager from failing.

If anyone has any other feedback, please let me know.

Thanks,
Severen
