Products block Orderby options

[claudiulodro]

Closes #55

Disclaimer: The WC API doesn't support ordering by sales, rating, and random and doesn't have filters for modifying it from the feature plugin to support them. We will have to add these features in API v3. Until then the Gutenberg preview won't accurately reflect the orderby setting sometimes, but the frontend will accurately reflect the orderby setting.

Can we add price asc/desc as order options?

I think we can lose the random order.

All seems to be working well otherwise!

We will have to add these features in API v3.

@claudiulodro Does that mean we need to log a new issue on the repo? I had a look around and couldn't find it anywhere - but that's all quite new to me.

@warrendholmes I've opened an issue at the repo. I don't believe the missing orderby options in the API should affect user testing.

I'll have @jameskoster's requested changes today.

EDITED: I've added support for price ordering and removed support for random ordering. Price ordering isn't supported in the API, so I've updated this issue to also document we need support for that. Price ordering should work fine on the frontend, just not in the preview.

[claudiulodro]

Opened a PR for the new orderby features we need.

[jameskoster]

I updated the labels. Hopefully I did everything right :p

Looks good @jameskoster 👍
