Use role-based access delegation for communication between AWS resources

[dmohns]

Reason: The project uses AWS access keys to authenticate with other AWS resources (S3). Usage of access keys is generally not recommended.

In our case the whole application runs on AWS infrastructure. So, it’s easy to implement key-less role-based authentication.

Steps:

• Setup role-based authentication in AWS
• Change the application and deployment method to use role-based authentication

Definition of done: No AWS accessKeys are required by the application.
