Feature: Delete topics

[mcandre]

Could we expose topic deletion through the kafka-python library? I would appreciate the ability to delete topics as a setup method in my integration tests, similar to how a PostgreSQL integration test would delete all records.

Unfortunately this is a limitation of Kafka currently. Deleting topics is non-trivial. It is generally better to let data age out of a topic when it is not longer needed instead of trying to manually prune the data as one would a database.

My understanding is that there is no way for a client to delete topics via the server API. Happy to revisit if that changes.

We already have support for this at the protocol level--this was added in #944.

Adding the AdminClient interface is tracked in #935
