Querier improvements for kava-4

[denalimarsh]

Queries are organized by module and priority. I'm working on implementing these on branch dm-queries.

• [1] First priority: there is currently no way to get this data
• [2] Second priority: active consumers need this data (and are mitigating with hacky solutions)
• [3] Third priority: "nice to have" for consumers

CDP

• [x] [1] Query CDP by ID
• [x] [1] Query total amount of savings rate distributed USDX
• [x] [1] Query CDPs by owner address (without collateral type)
• [x] [2] Query total amount locked for each collateral type
• [ ] [2] Query total amount borrowed for each principal type (currently just USDX)
• [ ] [2] Query total amount of savings rate distributed USDX by collateral type
• [ ] [3] Query total amount of fees currently outstanding
• [x] [3] Query total amount of fees that have been repaid (i.e. protocol profit)

Auction

• [x] [1] Query for auctions associated with a specific address. In this case the lotReturnAddrs from StartCollateralAuction.
• [x] [3] Use events to query closed auctions. -> develop a separate event storage/query service for our web app?

BEP3

• [ ] [2] migrate calculate-swap-id cmd from kvtool - it requires less args
• [ ] [2] marshal YAML gives bytes formatted swap ID
• [ ] [2] add marshalYAML (or String?) methods to swap direction and status types so they show up as string not numbers in query output
• [ ] [3] Consider adding ExpectedOtherChainSwapID to the augmented AtomicSwap.
• [ ] [3] Improve "atomic swap ID not found error" for claim txs. Example: https://lcd-kava-3.cosmostation.io/txs/DEF1D9CBC7A7E9A71B09EE0BD6DAA7B5DB4C3DF6D0CA06D3758C5BCEA9E32679

Incentive

• [x] [1] Query ongoing claims
• [ ] [2] Get reward APY for an asset at the current period reward rate. Under the current architecture, this should be a CDP module query because we need the amount of collateral locked and the collateral’s system price, requiring the import of CDP and Pricefeed keeper.

Feel free to modify the priority or add new queries to the list.

re

Query total amount locked for each collateral type

We already have this one I released. The CDP module account has all of the coins that have been deposited into cdps, so the endpoint /cdp/accounts (https://kava3.data.kava.io/cdp/accounts) shows the total collateral locked in cdps. We could add a convenience method, /cdp/accounts/cdp, to just query the cdp module account.
