[INFRA] [FT21-0] Create CloudFormation template for dex-roles stack

[MatheusMiranda]

Description

Currently, our customers configure their Athena/Glue/roles resources using a public terraform module shared by us.

To use this Terraform, the customers need to configure a whole terraform setup on their side; This is not a good experience for the customers and slows down the whole setup process.

Proposed Solution

To improve this process, we must create an analog CloudFormation stack, this way the customers can deploy the resources directly on AWS panel.

Additional comment

In addition to publishing the CloudFormation stack on our terraform-modules repository, we must publish the template in our public bucket, so we can reference the template directly during the user setup process.

Tasks

• Create a CloudFormation stack version of our dex-roles terraform module;
• Publish the template in both terraform-modules repository and in our public-assets bucket;
