Support multiple assume_role blocks in provider configuration for chained role use #91
Description
Describe the Feature
Provider should support multiple assume_role blocks in order to allow chained roles in some scenarios
Expected Behavior
Multiple assume_role blocks work just fine in hashicorp/aws
Use Case
In some scenarios there is a need to assume target role through a "proxy" role. Extremely useful in case of infra migrations or accommodating additional security requirements.
