test(e2e): lower cost to run on live networks (#1646)
* add cost summary to e2e test suite runs

* lower cost of test

* refactor initial funding to use new BankSend()

* reduce gas used for initial funding

* return all sdk funds on shutdown

* enable refunds when running against live network

* save more cosmos coins! require less total overall

* track erc20s on Chain

* refactor erc20 funding with new TransferErc20()

* return all registered erc20 balance

* lower erc20 e2e test values

* withdraw earn position & convert back to erc20

* lower gas fees in e2e tests

* fix env variable typo

* add readme note about how to run on live network

* log total spend required for e2e tests
