add initial E2E testing setup (#1475)

* setup e2e test that starts kava chain

* refactor into a testify suite

* setup ethClient

* add example test checking chain id

* cleanup

* refactor & support funded accounts with txs

* ignore e2e tests in CI & consolidate makefiles

* remove circular go.mod dependency

vendors `signing` and `grpc` packages from `kava-labs/go-tools` to
refrain from a circular dep and fix pulled in dep versions

* add min fee for evm side

* prune nothing in e2e node
