parse botocore.endpoint logs into a list of AWS actions (#49312)

* Add an option to parse botocore.endpoint logs for the AWS actions performed during a task

Add a callback to consolidate all AWS actions used by modules

Added some documentation to the AWS guidelines

* Enable aws_resource_actions callback only for AWS tests

* Add script to help generate policies

* Set debug_botocore_endpoint_logs via environment variable for all AWS integration tests

Ensure AWS tests inherit environment

(also remove AWS CLI in aws_rds inventory tests and use the module)
