Remove kafka support to reduce size

[mheffner]

Removing the Kafka exporter/receiver from the default build to reduce size and cold start time. This support seems less common for most use cases, so we'll exclude from the default image. Going to open issues to discuss building a separate layer for Kafka use cases.

This makes sense, but wanted to point out it will also disable aws_iam as it's in the default flag. Do you manually add it back when you build somewhere else?

We actually intentionally leave that out because it shouldn't be needed in the Lambda environment. The runtime environment manages IAM roles and sets temporary credentials with environment variables.

OK, cool I thought you might need it, but now I recall we added for the teleport ask.
