Off-chain views relating to liquidation auctions

[gkaracha]

Perhaps the Web UI will not offer functionality around liquidation auctions, but I think we could (and perhaps should) offer some off-chain views to assist users interacting with liquidation auctions. Let's discuss ideas about views that might be useful for users in this issue.

A few ideas to start with:

• Current winning bid
• Minimal amount of kit needed to place a bid
• How much tez is currently being auctioned off
• Blocks/Seconds passed since the last bid and how many remain until the auction closes

[gkaracha]

Also, we probably need to be able to find all slices / last slice sent to the auction queue, originating from a given burrow. Otherwise I don't know how would we be able to call entrypoint_cancel_liquidation_slice.

As far as I can tell, our current view exposes all basic information for interacting with the current liquidation auction:

val view_current_liquidation_auction_details: (unit * checker) -> view_current_liquidation_auction_details_result

type view_current_liquidation_auction_details_result =
  { auction_id: liquidation_auction_id
  ; collateral: tok
  ; minimum_bid: kit
  ; current_bid: bid option
  ; remaining_blocks: Ligo.int option
  ; remaining_seconds: Ligo.int option
  }

So, I think we can close this one.

The only thing that is missing now is a view for identifying slices whose liquidation can be cancelled (see my comment above), but that is not for participants in liquidation auctions, but rather for burrow owners. Let's open a separate issue for that (still low priority).
