Ensure random ads code branch is exercised by the load generator

[jlawrienyt]

Changes

• Add a new product in a new category, "Books"
• Update load generator script to fetch the new product, as well as request ads in the new book category, and request ads without any category, in order to test the random ad delivery code path
• This is in preparation for adding custom business metrics to the ad service.

Hi I wonder if 'This is in preparation for #73.', what metric do you want to provide if this pr is merged?

I was thinking of an ad requests counter with two dimensions: request type of either targeted or "not targeted", and response type of either targeted or random.

Do we have permission to use this image from National Geographic?

Maybe it was mentioned in a SIG meeting that I missed, but can we get a detailed plan in the #73 issue? I'm ok with adding another product and category, but if this is in reference to that issue, I would like to understand what the bigger picture looks like.

Hmm, good point. Any tips on where to get images where licensing won't be an issue? Alternatively, we don't strictly need to add a new product in order have the load generator exercise the random ads code branch since the load generator is hitting the ads API directly.

Sorry, I didn't realize this would be appropriate fodder for the SIG meeting. I'm happy to bring it up at the next meeting.

I've updated the new product to use a creative common licensed image.

Providing color in issue #73 itself would be fine as well. I just want to understand the big picture.

I've added a couple of paragraphs describing my general proposal in #73, let me know what you think.
