Product Search (v1p3beta1)

This Pull Request adds the code samples for cloud.google.com documentation for Product Search How-to Guides

Product Search How-to Guides –> vision/product-search/docs/how-to

products.js

• create_product
• get_product
• list_products
• delete_product
• update_product_labels

productSets.js

• create_product_set
• get_product_set
• list_product_sets
• delete_product_set

–> Products in productSets.js

• add_product_to_product_set
• list_products_in_product_set
• remove_product_from_product_set

referenceImages.js

• create_reference_image
• get_reference_image
• list_reference_images
• delete_reference_image

similarProducts.js

• get_similar_products_file
• get_similar_products_uri

importProductSets.js

• import_product_images
  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.

@beccataylor @JustinBeckwith
Please let me know if this makes more sense. Created a new branch - rebased and including all the Product Search related code. If this seems ok, will go ahead and close the old PR (#192).

Fixed the nits. Please approve.

Thanks! There are still many instances of var. Would you mind switching these to let / const?
