Swagger: Modernize application and update dependencies #1426
Description
This sample code seems to be really outdated. Code changes are needed to bring it up to date. But that just makes sense if this samples is still relevant which I don't have the context to know.
@SurferJeffAtGoogle and @simonz130, you seem to have been the main contributors to this sample in the past. Can you give more context as to whether this sample is still being used or not, etc.?
