Transition _cents fields to display_.._dollars fields (for non USD auctions)

[mzikherman]

In order to enable non USD auctions, recent PR's in gravity (https://github.com/artsy/gravity/pull/9179 as an example), has added JSON fields to help currency formatting.

So, any field relating to bidding that was of the form _cents (such as estimate_cents), now will also include a display_estimate_dollars field. This field (a string), will include any currency information, as well as proper formatting/rounding.

This makes it easier to actually put on a non USD auction, as clients can become 'dumber' and just render these fields directly, rather than doing a divide by 100 and add a $ sign, type thing.

This is fully backwards-compatible (it's just extra JSON) so no rush, but it would be nice (and I think net code deletion for you guys) to switch to this.

Here's an example of how Force was updated to use it: artsy/force#3334

Will open this issue in Eidolon as well.

Thanks guys! Let me know if you have questions.

Hey Matt! I know it's been a while since this was opened, just want to check in and see if this was still the plan?
