Migrating Auction samples to gateway

[nikhil550]

The auction samples are built in Javascript using the old gateway and connection profiles. What is the preferred way to migrate those applications to the new Fabric Gateway, which is documented mostly in TypeScript? I am starting to investigate that work as a way to familiarize myself with the new applications.

One differentiator is that the auction samples use the node.js FabricCAServices to register and enroll new users, where as the gateway samples use credentials that were generated by the Fabric-ca-clieint.
