  This last sample has been newly added after looking into the python and Java samples for comparison.

For the canonical versions, please see the Python Product Search Samples in python-docs-samples

These samples are in Beta and require using the v1p3beta1 API endpoint:

const vision = require('@google-cloud/vision').v1p3beta1;
const client = new vision.ProductSearchClient();

Before being ready for review & merge:

• Tests and linter pass
• Code coverage does not decrease (if any source code was changed)
• Appropriate docs were updated (if necessary) - working on this one - README is not getting updated with the Product Search code - looking into it.
