URL where issue was found: #[3.1. Connecting an AWS account to the Red Hat Hybrid Cloud Console

Description of issue: Update Prerequisites section for AWS integration for "Launch images" application. While creating an AWS source for "Launch images" application using the "Account Authorization Method", customers are uncertain about the required IAM user permissions. Should the IAM user have Administrator access, or can we set  limited permissions? what exact IAM permissions such AWS users should have. Normally, no one uses such broad permissions(admin) so the customer is looking for a particular IAM configuration. This is not even explained in our documentation.
 

Need to add a prerequisites section in the doc which explains which specific permissions are required for the AWS user who is going to mention their AWS Access key ID and Secret access key for "Launch images" application .
