support AWS IAM for authentication

[drummerwolli]

There are a lot of managed services in AWS. The easiest integration in regards to authentication to other services is usually IAM permissions (preferably IAM Roles).

It would be great if i could configure in Nakadi IAM Roles to consume from a certain Event Type.

Specific use-case: Read Event Types from AWS Kinesis Data Analytics (backed by Apache Flink) or AWS Lambda functions. So we can get rid of maintaining our own Flink Clusters.
