Unplanned Copr outage - 2022-07-08 and 2022-07-09

[Pavel Raiskup]

Copr failed to allocate VMs and assign VMs to the build task for several hours
now, which lead to many build failures.  Please restart the builds if you were
affected.  The issue is tracked here: https://pagure.io/copr/copr/issue/2066

Sorry for inconveniences.
