Describe the feature

Create a method that will allow users to add an IAM role to an already created cluster. This would allow a user to do the following:
myCluster.add_role(myRole)

Use Case

I'm always frustrated when I can't add a role to an already created cluster, and instead need to add it to the cluster on creation.
