Create a new AdminClient for making topics, partitions, and more. This is a factory method because it immediately starts an active handle with the brokers.

Create a topic. Just returns the string you gave it right now. Looks like a class, but all it does is return the topic name. This is so that one day if there are interface changes that allow different use of topic parameters, we can just add to this constructor and have it return something richer

Create a topic partition. Just does some validation and decoration on topic partitions provided. Goal is still to behave like a plain javascript object but with validation and potentially some extra methods
