According to CLOUD-70, we are not going to use credentials in S3 but the instance will have attached a role with the needed permissions. Thus, we need to update the aws-s3-connector code to:

• Do not validate whether the credentials exists
• Create the s3-client and presigner without credentials.

We will use the following configuration variables to detect when this is needed or not:

• magnolia.aws.validateCredentials
• magnolia.aws-s3.useCredentials
