liquid staking (#1273) * proto types * proto generated types * liquidstaking top level files: module, genesis * liquidstaking types * liquidstaking keeper * liquidstaking client/cli * add liquidstaking to app, simapp * implement mint derivative * set up liquidstaking keeper test suite * test mint derivative * rename module to liquid * rename proto types, app.go to liquid * use sdk.Coin instead of shares * mint liquid tokens to delegator * burn derivative tokens to receive delegation * use conversion method instead of type cast * simplify delegation transfer logic * broaden delegation transfer tests * simplify transfer delegation method This removes a source of rounding errors * move derivative denom to keeper config * check for invalid coins in msg validation * block 0share transfers to avoid handling edge case * refactor MintDerivative to test calculations * simplify burn method so shares and tokens equal * convert TransferShares back to old design this makes handling vesting tokens easier * fix missed merge conflict * remove deprecated constants * tidy up msg.go * add msg tests * remove unused store key * fix msg event sender * remove unused params * tidy up documentation and errors * remove unused mocks * remove unused keepers from AppModule * tidy up msg return values keeper return values to be used in router msgs * reinstate unintentionally removed interface check * catch invalid input for MnitDerivative clear up test TODOs * clear up InitGenesis TODO * Update x/liquid/client/cli/tx.go Co-authored-by: Derrick Lee <derrick@dlee.dev> * Update x/liquid/client/cli/tx.go Co-authored-by: Derrick Lee <derrick@dlee.dev> * show error logs in devnet * unblock mod account so it can receive dist rewards * catch zero amout msgs early * minor cli fixes Co-authored-by: rhuairahrighairigh <ruaridh.odonnell@gmail.com> Co-authored-by: Ruaridh <rhuairahrighairidh@users.noreply.github.com> Co-authored-by: Derrick Lee <derrick@dlee.dev>
