ACCEPTANCE CRITERIA

• When creating a workload with 'oc new-app' that points to a manifest-listed image, users should be able to set an "--import-mode=" flag to 'PreserveOriginal' in order to preserve all architectures of the manifest list  
• 'oc new-app --name <name> <manifestlist-image> --import-mode=PreserveOriginal' should not cause pods to fail due to being the incorrect architecture 
• Ensure node scheduling happens properly on a heterogeneous cluster when running 'oc new-app' with '--import-mode=PreserveOriginal'
