* Update doc of AnsibleAWSModule to remove incorrect connect example.
Current example uses aws_connect method which no longer exists. Replace
this with the client and resource methods that do exist.
Also remove try/except block in connect example as guidelines imply that
there aren't connection errors thrown on connection, just when later
sing the connection.
* Update AWS module guidelines to include the AnsibleAWSModule connection methods.
* Add information on integration testing to the AWS module guidelines.
* Add information on common documentation fragments to AWS module
Guidelines.
* Changes as requested on PR.
* Restructure connection section to start with current best practice
* Explain the use of the CI build groups
* Use YAML Anchors for aws credentials example
* Replace guidance on use of test groups with link to aliases file.
This achieves the goal of explaining why this file is necessary without
introducing overhead of keeping documentation up to date when test
groups change.
* Remove redundant default for target_paths
* Make invalidation requests idempotent
* Remove redundant exception handling around boto3_conn
* Add cloudfront_invalidation to the changelog
_name attribute is used when providing generic error messages
(such as connection problems). As AnsibleAWSModule does not inherit
things from AnsibleModule by default, need to provide it.
