Subject: [PATCH container v2] api: record CT ID as used after a container is destroyed
Date: Fri,  4 Oct 2024 18:07:42 +1300
Message-ID: <20241004050957.441759-4-severen.redwood@sitehost.co.nz>

After a container is destroyed, record that its ID has been used via the
`PVE::UsedVmidList` module so that the `/cluster/nextids` endpoint can
later optionally avoid suggesting previously used IDs.
