Hard: liquidation by keeper (#731)
* hotfix * update params, keys * liquidation by keeper * refactor GetPendingBorrowBalance * fix app build * elegant handling of denom arrays * auction deposit in lots * add error msg * update tests with new params * happy path liquidation test * update liquidator macc name * refactor reward % to money market params * refactor tests for updated params * compile: harvest liquidator module account * add liquidate msg * liquidation approach * update liquidations * return remaining deposit coins to original borrowr * check keeper reward before sending * introduce ValuationMap * convert Ints <> Decs * implement double-loop * ModuleAccountName * sort keys for deterministic auctions * test: correct auctions created * test: preset keeper coins * ensure deterministic iteration * test cases * update repay test * auction fixes, tests
