Datasets Dependency Management Tutorial Does Not Work

[bencaldwell]

Describe the bug
I am trying to follow the tutorial for dataset dependencies at
https://github.com/awslabs/aws-serverless-data-lake-framework/blob/master/sdlf-utils/pipeline-examples/dataset-dependency/README.md
I can not make this work. Perhaps there is a step missing from the readme?

To Reproduce
Steps to reproduce the behavior:

1. Provision the datalake as per the SDLF workshop
2. Deploy the pipeline from stageA directory using sam build; sam deploy --guided --capabilities CAPABILITY_NAMED_IAM
3. Deploy the dataset from dataset directory using sam build; sam deploy --guided --capabilities CAPABILITY_NAMED_IAM
4. See error Pipeline doesn't exist or inactive

Expected behavior
I expected to see an entry for the new dataset in dynamoDB table octagon-Datasets-dev after running the above. Then I could update dependencies as per the tutorial and see the step function succeed.

I'm fixing this one.
