Description

It would be nice if there was an option to multiple instance types to fleet configuration. When using aws emr create-cluster, this can be done by passing an argument like InstanceTypeConfigs=['{InstanceType=m5.xlarge,BidPrice=0.5,WeightedCapacity=2}']

Research direction
Investigate the current implementation of EMR cluster creation in the aws sdk pandas library. Look for the function that handles create cluster and see how instance types are currently specified. The user wants to extend it to support multiple instance types via InstanceTypeConfigs. Check the existing code for any similar patterns and test coverage. Consider the trade offs between adding a new parameter and modifying the existing one.
