* Update testing policies to ensure all required permissions are present
* Tidy up security policies to reduce duplicate permissions
* Make roles static so that they can be present before CI is run,
meaning that role creation permission is not required by the CI
itself, only by someone setting up the roles prior to testing
* Move contents to cloudfront policy to network policy to ensure policy
count (maximum of 10) stays low
* Maintain compute policy below 6144 bytes
* AWS: new module ec2_transit_gateway fixes#49376
* Add permissions neeeded for integration tests
* uncomment nolog on creds
* add unsupported to integration test aliases
* remove the shippable/aws/group alias so doesn't conflict with unsupported
Remove VPC permissions from network-policy.json as they mostly duplicate
compute-policy.json permissions - separating the VPC and compute permissions
would likely lead to further confusion.
