Add instrumentation for Kafka Sarama Library

[grcevski]

Is your feature request related to a problem? Please describe.
Currently the Kafka instrumentation we have in the project is instrumenting kafka-go from segment.io, however Shopify/IBM Sarama seems widely popular as well and it's used in the OpenTelemetry DEMO. It would be nice to add instrumentation for Sarama so that we can demo the auto-instrumentation capabilities with the OpenTelemetry DEMO. Checkout service is a producer, while Accounting service is a consumer.

Describe the solution you'd like
Add new Kafka instrumentation support for both the producer and the consumer paths for Shopify/IBM Sarama.

Describe alternatives you've considered
Not having the library instrumented
