Implement Hard strategy for Earn vaults (#1278)
* Simplify strategies to lend and savings

* Add hard and savings keepers

* Add ctx to strategy interface, fill in lend strategy

* Rename lend strategy to hard

* Fix hard deposit query, fix withdraw bank send

* Fix misleading borrow instead of withdraw for hard

* Remove liquidateall strategy method

* Withdraw tests

* Add hard gs to testutil suite

* Update withdraw tests with working hard strategy, clean strategy interface methods

* Check allowed denom for strategy

* Update GetVaultTotalValue doc note

* Update error wrap message for unsupported denom

* Remove unnecessary viewvault keeper

* Withdraw amount from account value, not supplied value

* Test value > supplied withdraw

* Use dec when dividing for withdrawAmountPercent

* Use the correct store prefix for vault shares

* Update swap references to earn

* Simplify vault shares, use a single share for all coins per address
