Refactor incentive payout (#953), Users can claim swap rewards (#955)
* split up payout.go file

* extract genesis builders to new testutil package

* move claim integration tests out of keeper

* convert claim integration tests to handler tests

* combine claim usdx minting keeper methods

* combine hard claim keeper methods

* combine delegator claim keeper methods

* add multiply coins helper method

* rename file to better match contents

* add basic claiming unit tests

* add claiming subset of delegator reward denoms

* refactor msg tests

* add msg ValidateBasic tests

* connect swap hooks into keeper methods

* tidy up delegator handler tests

* add swap claiming msgs and keeper method

* add swap claiming to client

* add subset claiming to other msg types

* split up handler test file

* connect up subset claiming for swap

* make multiplier name validation more strict

* fix: struct tag typo in swap incentives

* connect up subset claiming for hard

* connect up subset claiming for delegator

* fix: register cli tx routes for swp claiming

* fix claim amount in claim event

* fix token name in cli help docs

* remove unused field in msg tests

* tidy up swap and delegator handler tests

* refactor hard handler tests

* refactor usdx handler tests

* remove unused constant
