Support for auto-instrumentation of Confluent Kafka .NET Client 2.x

[stevejgordon]

The profiler-based instrumentation is currently enabled for v1.4.0 and newer, but only in the 1.x major version. We need to review the API for breaking changes and evaluate support for v2.x clients.

Hi @stevejgordon, I wonder if there is any plan to support this shortly.
