SDK Generation Failing Since Child Namespace is Defined Before Parent Namespace in Staging Beta Metadata

[fey101]

The root cause is actually traced to Vipr.Reader.OData.v4.OdcmReader.ReaderDaemon.WriteNamespaces() method where ordering of namespaces in such a way that the child namespace appears before the parent namespace prevents correct evaluation of KeyProperty 'Id' of the EntityType "lifecycleWorkflowsContainer during generation of its OdcmModel.

The issue is already submitted on the Vipr repo here: microsoft/Vipr#254

Suggested Fix: Either reorder namespaces in the metadata preprocessing step so that the parent namespaces always appear before the child namespaces or incorporate the reordering logic within Vipr.
