When trying to create a new compute-resource via API (e.g. foreman-ansible-modules or hammer), the request fails with Datacenter can't be blank

$ hammer compute-resource create --provider="VMWare" --name "vCenter" --description "Test vCenter" --user "administrator" --server "vsphere.example.com" --password 'secret' --datacenter "DEV" 
Could not create the compute resource:
  Datacenter can't be blank

I suspect the change from #30372 to be the reason for this, because it removes the datacenter-option from the compute-resource create instruction.
