Tail for nested stacks

[atkinsonm]

I commonly use nested stacks to strike a balance between modular code and built-in references and dependencies in CloudFormation templates. When using cfn-tail, only events on the AWS::CloudFormation::Stack resource will show. This is because CloudFormation shows the child stack's events under its own resource.

I'd like cfn-tail to recursively perform describeStackEvents calls if it detects an event.ResourceType === "AWS::CloudFormation::Stack".

I submitted a feature request to AWS a while back requesting support for a way to show all nested stack events by querying the root stack. That would go a long way towards supporting this.
