[pdm-devel] [PATCH proxmox-datacenter-manager 1/1] tree-wide: handle new unknown enum variants

[Stefan Hanreich]

pve-api-types now generates a fallback enum variant in order to handle
encountering unknown values for enums more gracefully. Fix all
occurrences of enums that have changed that lead to compiler errors.

In the case of migrations an error is thrown, since it is impossible
to tell if it is okay to proceed migrating a guest with an unknown
state. In other cases simply log / print the unknown value.
