Need to clean up region tags

[JustinBeckwith]

This feels like a weird place to start a snippet. Is that intentional?

[nnegrey]

Yep, the START and END pieces allow us to show one piece on the docs while keeping the majority of the sample the same.

One file: https://github.com/googleapis/nodejs-automl/blob/master/samples/list_datasets.js

Docs:

1. https://cloud.google.com/natural-language/automl/docs/manage-datasets#automl_language_text_classification_list_datasets-nodejs
2. https://cloud.google.com/natural-language/automl/docs/manage-datasets#automl_language_text_classification_list_datasets-nodejs

For my own understanding - are these features available in the GA version of the API? Or only in the beta?

[nnegrey]

The video flavor of AutoML is in beta along with Tables

But these other versions are in GA:

• Language: Entity Extraction, Sentiment Analysis, Classification
• Vision: Object Detection, Classification
• Translate

@nnegrey happy to help land these updates (I saw a few similar PRs) once @JustinBeckwith's comments are addressed. Please feel free to flag me once you're ready.

@nnegrey we might want to eventually take the multiple-region-tags-in-one-file case into account when generating README files, based on region tags.
