Implement the standadized CLI for execution state transition tests

[zah]

https://ethereum-tests.readthedocs.io/en/latest/t8ntool-ref.html is a document describing a standard command-line interface for executing state transition tests. There are third party testing teams interested in including Nimbus in their testing efforts, but their existing tooling is based on this standardized interface.

I've implemented the state transition tool in PR #1279. And here is the build instructions:

Thanks, I will check it out

[winsvega]

please support

--state.reward -1

for genesis state hash calculation (to calculate given state hash without any 0, or non 0 mining rewards)

Thanks a lot lets see which tests do yo pass. but first I need this option. we recently discoverd a bug in the tests that lead to coinbase account not being present in the state with 0 reward touch. (pre EIP150) rules. but this also means that when I calculate genesis state hash, I don't need coinbase account touch on pre EIP150 rules. so -1 means just calculate the stateRootHash of the given state. which I use to process genesis.

I put it here #1313
