Update Documentation to Reflect Credential Requirements

[mcdonnnj]

🚀 Feature Proposal

Update the documentation to reflect the credentials you need to have in place to successfully perform Terraform actions on AWS.

Motivation

After rolling a set of credentials, I had not updated my AWS credentials configuration to reflect the change. This resulted in a failure when trying to perform Terraform actions because although I had appropriate credentials in place for the AWS account the EC2 instances reside in, I did not have valid credentials for the provider that handled DNS resources.
