Simple example demonstrating a problem with Enhanced Fan-Out KCL Consumers against Localstack

Based on https://docs.aws.amazon.com/streams/latest/dev/building-enhanced-consumers-kcl-java.html but tweaked to work with Localstack.

Duplication steps:

1. Start localstack:

docker-compose up --build -d

2. Create a Kinesis stream:

aws kinesis create-stream --stream-name efo-test --profile localstack

3. Run the application and wait for the errors to happen. The time it takes for the error to happen is equal to the apiCallTimeout setting on the Kinesis client
