Add E2E Swap Support (#959)
* add message types for swaps * add tx client commands * add test coverage for swap message deadlines * start handler swap tests, export handler result message event into private method, add stubbed keeper methods * add initial swap implementation to get handler tests passing; adds event specific for trades * add handler acceptance test for slippage in exact input and exact output swaps * implement slippage limit for swap keeper methods * add tests to ensure a user can only swap spendable coins * test pool not found, panic on invalid pool, and panic when module account does not have enough funds * validate that the exact output when using for exact swaps is less than the pool liquidity * nit: long line * add validation that swap output is greater than zero * add rest txs for swap messages * nit: lints * dry up swap keeper methods * from pr feedback - spelling and increase clairty around the output amount of a swap rounding to zero
