rain should support "service-managed" stacksets

[paul-e-allen]

I am deploying CloudFormation templates that create stacksets as resources. I thought I might be able to use the rain stackset ls TARGET_STACKSET to watch the deployment of the stacksets.

When I executed just a plain rain stackset ls I noticed that rain is showing only the "self-managed" stacksets and not the "service-managed" stacksets.

When I try to execute a rain stackset ls TARGET_STACKSET when the target stackset is "service-managed", that generates the following error:

failed to list stack set 'stacksets-gitsync-test-team-chatbot-limited-regions-regional': operation error CloudFormation: DescribeStackSet, https response error StatusCode: 404, RequestID: 0d95366b-8326-4c2a-9600-9f1eb9ca1fc7, StackSetNotFoundException: StackSet TARGET_STACKSET not found

I am using Rain v1.7.5 linux/amd64.

It would be awesome if rain supported "service-managed" stacksets.

The API has a CallAs parameter that we need to set, so I think this should require you to specify it on the command line.

rain stackset ls --call-as admin

The default for call-as will remain self

type CallAs string

// Enum values for CallAs
const (
	CallAsSelf           CallAs = "SELF"
	CallAsDelegatedAdmin CallAs = "DELEGATED_ADMIN"
)

Maybe simpler to do this:

rain stackset ls --admin

And assume self otherwise
