### Summary

As a new contributor to AWS modules, I assumed that the default permissions used by the cli would be used by the tests.
When I run `ansible-test integration lambda -v` I get:

```
WARNING: Excluding tests marked "cloud/aws" which require config
(see "/home/dev/ansible/ansible/test/lib/ansible_test/config/cloud-config-aws.ini.template"): lambda
```

This message is not clear.
e.g. do I just edit that file in-place? Do I edit it and then rename it to remove `.template` from the name? 
The answer is neither of those.
Apparently you're supposed to copy the modified file somewhere else. This is not obvious to new users.
So I propose that the error message be changed to say:

```
WARNING: Excluding tests marked "cloud/aws" which require config
(see "/home/dev/ansible/ansible/test/lib/ansible_test/config/cloud-config-aws.ini.template" which must be copied to something/integration/test and modified): lambda
```

(Where `something` is the real directory)

Additional changes:

* the `.template` files should have a comment inside saying what to do with them. i.e. which folder to put them in. Or there should be a README next to the .template files stating that.
* the AWS one specifically should have a comment stating what to do for fields like `security_token` when your credentials don't have such a token.
