* AnsibleAWSModule related cleanup - redshift
* Apply a backoff on modify_cluster to cope with concurrent operations
* Add AWS 'hacking' policy to allow creation of Redshift ServiceRole
* Adding the retry policies makes the redshift test suite more reliable
* 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
* Update testing policy to be correct for RDS test suite
* Create read replica in same region to avoid more permissions being
required
* Ensure modifying DB doesn't try to downgrade engine version
* Add tags to main test suite to limit number of tests run for problem
solving
* Combine testing policies
Because of the maximum of 10 policies per group, need to
consolidate testing policies as best we can.
* Tidy put-account-setting tasks and add permission
Using `environment` and `command` rather than `shell` avoids the
need for `no_log` and means that people can fix the problem
* refactor ecs_cluster test suite
move from runme.sh technique to virtualenv
use ec2_instance rather than ec2 module to
avoid need for boto
