How can we return a list of all the created dependency resources?

[martinsawicki]

Creating pretty much any resource can result in the creation of at least one additional associated resource (at minimum a new resource group). It would be useful to return a list of all the implicitly created resources when a given resource is called so that user code can easily identify them and possibly delete them later as part of cleanup, if they do not want to rely on resource groups for that purpose for one reason or another.

Now, because of Azure's createOrUpdate semantics, and the lack of a truly atomic "createIfNotAlreadyExists" operation in Azure, we cannot return a list of resources that were truly created -- Azure does not give us that info. It is possible that some of the resources we think we are creating already exist - we can't reliably tell the difference today.

But perhaps it is enough for such scenarios if the SDK APIs simply return the list of all the resources that were intended to be created (and are now in existence). We could do at least that much rather easily, via perhaps a create(List<Resource> resourcesCreated) -- we could populate the resourcesCreated list provided by the user code with what we already track internally as created resources in the graph impl.

do we have any way to get list of created resources of a deployment? This will be helpful to delete specific deployments from a resource group or roll back a specific deployment in case of failure.

PR #1300 should help quite a bit with enabling this need as it gives developers real-time visibility into what gets created under the hood.
