late initialize fields that get defaulted by AWS (#255)

Issue [#2695](aws-controllers-k8s/community#2695)

Description of changes:
Some spec fields get default values from AWS after they are created.
These defaults cause the controller to keep requeuing, trying to set
them to null. With these changes, we late initialize these fields, 
ensuring they are defaulted if the user does not define them
