Docs on filling out cf-stub should clarify non-overlapping requirements for domain, system_domain, and apps_domains

[Amit-PivotalLabs]

I don't actually know what the real requirements are to pass the validations in Cloud Controller, but it would be nice if the docs guided users to not misconfiguring these domains so they can avoid the validation errors that only surface late at deploy time.

Thanks, @Amit-PivotalLabs. We've updated the "Customizing the Cloud Foundry Deployment Manifest Stub for AWS" topic in our docs.

The documentation now covers system_domain and app_domain however one thing is still missing which is "domain". What is "domain" used for?
