openapi: Add EmptyResource/CreateOpenAPISchemaFunc test utils

Browse Source 
Add a new EmptyResource class that implements openapi.Resources, but
just doesn't have any resources. That is useful for tests that expect
the OpenAPISchema to be working, but don't expect any actual result.

Also implement CreateOpenAPISchemaFunc to simply plug in the TestFactory
code when you want to use an actual APISchema.
