Add liquidation kick support to bots

[yghazi]

Goal

Add liquidation kick support to bots, such that it will bark at under collateralized urns automatically instead of waiting for the Bark event.

Context

I need to create a keeper that will a, initiate liquidations and b, participate in said liquidations (with or without arbitrage opportunities). I've been looking at other keepers and this one seems like a good fit. Well-maintained, as it is. If there is such a keeper out of the box, I'd like to know.

hey @yghazi,
thanks for opening the issue.

The current keeper implementation supports detection and participation in collateral (flip), surplus (flap) and debt (flop) auctions. Auction initialisation (aka kicking of underwater vaults) is not yet included in the feature-set.
In case you want to test auction participation of your keeper instance you can
a) do so on goerli where there are auctions that just need to be restarted
b) run one of our auction simulations on a hardhat fork and test your keeper instance there

We've recently extended the UI with the functionality to kick underwater vaults (see: https://unified-auctions.makerdao.com/vaults?network=mainnet). So will definitely take a look into extending the keeper functionality in the similar direction and keep you posted.

In case you have any related questions, feel free to raise them here in the issue.

Appreciate the help. I'll look into it.
