test(e2e): support running against live networks (#1630)
* add NodeRunner impl for connecting to live network

* refactor out node runner setups

* remove hardcoded denom for DeployedErc20

* further specify restrictions on DeployedErc20

* don't override .env funded account mnemonic

* lower amounts for convert to coin e2e tests

* lower fund values used by e2e tests

* add doc comments for all e2e functions & types
